How to Get Prismatic Heart in The Forge (March 2026) Complete Guide
The latest Cave Update in The Forge has introduced one of the most sought-after legendary items in the game—the Prismatic Heart. If you’re working toward unlocking the powerful Dragon Head Pickaxe or looking to craft end-game weapons with a massive 5.5x multiplier, you absolutely need this rare ore. After spending countless hours farming spider caves and analyzing drop rates, I’ve put together this comprehensive guide to help you obtain the Prismatic Heart efficiently.
Whether you’re a new player just reaching Frostspire Expanse or a veteran looking to complete the Cult Questline, this guide covers everything from exact spawn locations to proven farming strategies that actually work. Let’s dive into the mysterious world of prismatic ores and get you that coveted heart!
What is Prismatic Heart in The Forge?
Before we jump into farming strategies, let’s understand exactly what makes the Prismatic Heart so valuable in The Forge’s current meta.
| Attribute | Details |
|---|---|
| Rarity Tier | Legendary |
| Drop Source | Spider Cave enemies (Frostspire Expanse) |
| Base Drop Rate | 1 in 33,333 (displayed) / ~1 in 15-50 (actual from Prismarine Spider) |
| Forging Multiplier | 5.5x |
| Primary Use | Cult Questline (Dragon Head Pickaxe) |
| Sell Price | High (varies with market) |
| Island Location | Island 3 – Frostspire Expanse |
The Prismatic Heart is a legendary-tier ore introduced in The Forge’s Cave Update that serves dual purposes: it’s both a critical quest item for unlocking the Dragon Head Pickaxe and an exceptional crafting material for end-game equipment. What makes it unique is its distinctive multicolored shimmer effect described in-game as having “too many colours to be safe.”
Why You Need Prismatic Heart
Understanding the importance of this ore will motivate you through the farming process:
Quest Progression: The Prismatic Heart is absolutely mandatory for completing Auron’s quest, which is the first of three Cult Quests required to unlock the Dragon Head Pickaxe—currently the strongest pickaxe in The Forge with 750 mining power and 78% luck boost.
Crafting Excellence: Beyond quest requirements, the Prismatic Heart provides a substantial 5.5x multiplier when used in forging, making it one of the best materials for crafting high-tier weapons and armor.
Passive Traits: When used to craft weapons, the Prismatic Heart grants exceptional passive abilities including 20% Critical Chance, 5% Critical Damage, and a 15% chance to slow enemies for 2 seconds (with an 18-second cooldown).
Long-term Investment: Extra Prismatic Hearts beyond the quest requirement are valuable for crafting multiple end-game weapons, making them worth stockpiling rather than selling immediately.
How to Get Prismatic Heart in The Forge
Now let’s get into the actual step-by-step process of obtaining this legendary ore. The journey requires meeting specific prerequisites and knowing exactly where to farm.
Prerequisites and Requirements
Before you can even attempt to farm Prismatic Hearts, you must meet these non-negotiable requirements:
Level Requirement: You must reach Level 70 minimum to access Frostspire Expanse (Island 3). However, I strongly recommend being Level 80-90 for comfortable farming, as the spider enemies can be challenging for undergeared players.
Portal Tool: Complete the early tutorial quests and speak with the Wizard NPC to unlock the Portal Tool, which is essential for traveling between islands.
Adequate Equipment: You’ll need decent combat gear to handle spider enemies efficiently. The spiders have significant health pools and can deal substantial damage, especially in groups. Consider crafting armor with at least Epic-tier ores and a weapon with good DPS.
Simple Lantern: Purchase the Simple Lantern from the Bard NPC for 350 gold. The Spider Cave has dark areas where visibility is crucial for efficient farming and avoiding unnecessary combat.
Health Potions: Stock up on Health Potions from Maria’s shop. I recommend bringing at least 5-10 potions to avoid constant trips back to town. Spider Cave farming sessions can last 30-60 minutes for optimal efficiency.
Step-by-Step Farming Guide
Once you’ve met all prerequisites, follow these exact steps to farm Prismatic Hearts efficiently:
Step 1: Travel to Frostspire Expanse
Open your Portal Tool (check your inventory or hotbar) and select Frostspire Expanse as your destination. The portal will transport you directly to Island 3’s spawn point near the icy landscape.
Step 2: Locate the Spider Cave Entrance
From the Frostspire Expanse spawn point, head toward the southwest area of the island. You’re looking for a cave entrance that you may have visited during the early Raven questline. The entrance is marked by ice formations and has a distinct cave opening.
Pro tip: If you’ve completed Raven Quest 1, you’ll already be familiar with this location. The Spider Cave is the same cave where you defeated spiders for earlier quest objectives.
Step 3: Navigate to the Prismarine Spider Location
Enter the Spider Cave and equip your Simple Lantern for better visibility. Navigate deep into the cave—you’ll pass through areas with smaller Crystal Spiders and Diamond Spiders. Continue pushing forward until you reach the deepest chamber where the Prismarine Spider spawns.
The Prismarine Spider is a mini-boss enemy that sits at the edge of the spider cave, typically surrounded by smaller spider minions. It’s larger than regular spiders and has a distinctive prismarine color scheme with enhanced visual effects.
Step 4: Combat Strategy for Prismarine Spider
Defeating the Prismarine Spider requires proper technique to avoid unnecessary deaths:
- Ranged Attacks: The Prismarine Spider attacks from distance, so maintain spacing and dodge when you see attack animations.
- Minion Management: Clear smaller spiders first if they’re overwhelming you, or focus on the boss if your DPS is high enough to burst it down quickly.
- Healing Timing: Don’t wait until critical health to use potions. Use them proactively at 40-50% health to avoid panic situations.
- Dodge Patterns: Watch for telegraphed attacks and dodge sideways or backward. The spider has predictable attack patterns once you learn them.
Step 5: Farming Optimization
After defeating the Prismarine Spider, check your inventory for the Prismatic Heart drop. If it drops, you’ll see a notification with the distinctive multicolored ore appearing in your inventory.
If the heart doesn’t drop, wait for the boss to respawn (typically 2-5 minutes) and repeat the process. Here’s where the real farming begins, and I have specific strategies to maximize your efficiency.
Understanding Actual Drop Rates
There’s significant confusion about Prismatic Heart drop rates, so let me clarify based on extensive community testing:
Official Tooltip Rate: The game displays 1 in 33,333 chance, which sounds absolutely brutal.
Actual Tested Rate from Prismarine Spider: Community testing and my personal experience suggest the actual drop rate from Prismarine Spider is approximately 1 in 15 to 1 in 50 kills. This is significantly better than the tooltip suggests.
With Max Luck Modifiers: Using Luck Totems, Luck Potions, and races with luck bonuses (like Angel), players report drop rates improving to roughly 1 in 8 to 1 in 15 kills.
Crystal and Diamond Spiders: These smaller spiders have much lower drop rates (closer to the 1 in 33,333 displayed rate) and aren’t worth farming specifically for Prismatic Hearts.
This discrepancy between displayed and actual rates is common in The Forge—many legendary items have inflated displayed rates to maintain the perception of rarity while keeping actual acquisition reasonable.
Pro Farming Strategies
After farming dozens of Prismatic Hearts, here are advanced strategies that dramatically improve efficiency:
Strategy #1: Combine with Raven Quest 2
If you haven’t completed Raven Quest 2 yet, DO NOT farm Prismatic Hearts separately. Raven Quest 2 requires killing 1 Prismarine Spider and 10 Diamond Spiders. Accept this quest first, complete it while farming, and you’ll likely get your Prismatic Heart during the process. This saves you an entire farming session.
Strategy #2: Private Server Farming
Consider using a private server (requires Robux) if you’re serious about farming. Public servers have competition for Prismarine Spider spawns, and other players can tag your boss, forcing shared drops or even stealing kills. Private servers give you exclusive access to respawns, cutting your average farming time from 1-2 hours to 20-45 minutes.
Strategy #3: Luck Stacking
Maximize your luck stat through every available means:
- Equip any pickaxe or weapon with luck bonuses
- Use Luck Potions from Maria’s shop
- Activate Luck Totems if you have them
- Choose races with luck bonuses (Angel provides +10% luck, the highest in-game)
- Participate during 2x Luck weekend events when available
Community data suggests luck stacking can cut your farming time in half by improving drop rates on legendary items.
Strategy #4: Ice Pebble Gold Farming Between Respawns
Don’t waste time standing around waiting for Prismarine Spider respawns. Between boss kills, quickly farm Ice Pebbles near the cave entrance for steady gold income. Ice Pebbles respawn rapidly and provide decent gold per hour, making your farming session profitable even before getting the Prismatic Heart.
Strategy #5: Form a Farming Party
While The Forge doesn’t have official party mechanics, coordinating with other players can help. Take turns tanking the boss, share healing responsibilities, and celebrate drops together. Just establish clear loot rules beforehand to avoid disputes.
What to Do With Your Prismatic Heart
Once you’ve finally obtained your Prismatic Heart (congratulations!), you have several options for using it wisely.
Primary Use: Cult Questline Progression
The most important and recommended use for your first Prismatic Heart is completing Auron’s Cult Quest. Here’s the complete questline context:
Auron’s Quest (First Cult Quest):
- Location: Corruption’s Heart chamber in Raven Cave
- Requirement: Turn in 1 Prismatic Heart
- Reward: Quest progression toward Dragon Head Pickaxe (1/3 hearts collected)
- Next Steps: After completing Auron’s quest, you’ll need to collect a Yeti Heart and Golem Heart for the remaining two Cult NPCs
The Complete Cult Questline:
- Auron (Right NPC) – Requires Prismatic Heart
- Mjelatkhan (Center NPC) – Requires Yeti Heart (drops from Yeti enemies in Peak Cave, 1 in 44,444 displayed rate)
- Morveth (Left NPC) – Requires Golem Heart (drops from Ice Golem Boss at Summit’s Edge, 1 in 55,555 displayed rate)
After completing all three quests, the Dragon Head Pickaxe becomes available for purchase for 2,750,000 gold. This pickaxe features 750 mining power, +15% mining speed, +78% luck boost, and 4 rune slots—making it the undisputed best pickaxe currently available in The Forge.
Secondary Uses: Crafting and Selling
If you’re fortunate enough to obtain multiple Prismatic Hearts, consider these alternative uses:
Weapon Forging: Use Prismatic Hearts to craft exceptional weapons with the 5.5x multiplier and powerful passive traits. The 20% Critical Chance and 5% Critical Damage make it ideal for DPS-focused builds. Weapons crafted with Prismatic Hearts consistently outperform those made with lower-tier materials.
Armor Forging: While less common, using Prismatic Hearts in armor provides the same 5.5x multiplier for defensive stats. This is particularly valuable for tank builds that need maximum survivability.
Selling for Gold: Prismatic Hearts sell for substantial gold amounts at Greedy Cey’s shop. However, I strongly recommend against selling your first few hearts. Save them for crafting after completing the quest, as their crafting value far exceeds their immediate sell price.
Future Updates: The Forge developers regularly add new content requiring legendary materials. Stockpiling extra Prismatic Hearts may give you a head start on future questlines or recipes.
Prismatic Heart Farming Timeline
Let’s set realistic expectations for how long farming will take based on different scenarios:
Scenario 1: Optimal Conditions (Private Server + Max Luck + High Level)
- Expected Time: 20-45 minutes
- Kill Count: 8-20 Prismarine Spiders
- Success Rate: 95%+ within 1 hour
Scenario 2: Good Conditions (Public Server + Some Luck + Adequate Level)
- Expected Time: 1-2 hours
- Kill Count: 15-50 Prismarine Spiders
- Success Rate: 80% within 2 hours
Scenario 3: Challenging Conditions (Public Server + No Luck + Min Level)
- Expected Time: 2-4 hours
- Kill Count: 30-100+ Prismarine Spiders
- Success Rate: 70% within 4 hours
These timelines assume efficient farming with minimal downtime. Remember that RNG can be both friend and foe—some players get their Prismatic Heart on the first kill, while others might need 50+ attempts. Patience and persistence are key.
Common Mistakes to Avoid
After observing countless players attempt to farm Prismatic Hearts, here are the most common mistakes that waste time and resources:
Mistake #1: Farming Crystal or Diamond Spiders
Many beginners spend hours killing smaller spiders thinking they have equal drop chances. The reality is that Crystal and Diamond Spiders have dramatically lower drop rates. Always prioritize the Prismarine Spider boss for efficient farming.
Mistake #2: Attempting at Too Low Level
Arriving at Level 70 with basic equipment leads to constant deaths and healing costs that exceed any potential gains. Wait until Level 80+ with decent gear before seriously farming Prismatic Hearts.
Mistake #3: Ignoring Luck Modifiers
Farming without any luck bonuses significantly extends your farming time. Even basic Luck Potions (which cost minimal gold) can improve your rates noticeably. Never farm legendary items without at least one luck modifier active.
Mistake #4: Selling Your First Prismatic Heart
The immediate gold from selling might seem tempting, especially if you’re broke, but completing the Cult Questline to unlock the Dragon Head Pickaxe provides far more long-term value. The pickaxe’s mining efficiency will earn back that gold many times over.
Mistake #5: Farming Solo in Crowded Public Servers
Public servers during peak hours create frustrating competition for boss spawns. Either find a low-population server, farm during off-peak hours, or invest in a private server for serious farming sessions.
Mistake #6: Not Bringing Enough Supplies
Running out of health potions mid-farming session forces you to travel back to town, losing your cave position and wasting 5-10 minutes per trip. Always overstock supplies before starting a dedicated farming session.
Advanced Tips for Veteran Players
If you’ve already obtained your first Prismatic Heart and completed the Cult Questline, here are advanced strategies for maximizing your prismatic ore collection:
Multi-Heart Farming for Multiple Weapons
Once you’ve secured the Dragon Head Pickaxe, consider farming additional Prismatic Hearts to craft multiple legendary weapons. Having a Prismatic-enhanced sword, axe, and bow gives you versatility for different combat situations and enemy types.
Market Timing for Sales
If you’re selling Prismatic Hearts, pay attention to game events and updates. Prices typically spike after patches that introduce new content requiring legendary materials. Selling during these periods maximizes your profit margins.
Combining with Other Heart Farming
Since you’ll be farming Yeti Hearts and Golem Hearts for the other Cult Quests anyway, create an efficient farming route: Spider Cave → Peak Cave → Summit’s Edge. This circuit approach prevents burnout from farming a single location repeatedly.
Recording Your Drop Rates
Keep a spreadsheet or notepad tracking your Prismatic Spider kills versus Prismatic Heart drops. This personal data helps you identify your actual drop rate with your specific luck modifiers and can inform future farming decisions.
Alternative Sources and Future Updates
Currently, the Prismarine Spider in Spider Cave is the only practical source for Prismatic Hearts. However, The Forge developers frequently add new content, so stay alert for:
Limited-Time Events: Seasonal events sometimes offer legendary materials as rewards or have boosted drop rates. The Christmas Event (March) featured increased luck for rare materials.
Quest Rewards: Future questlines may reward Prismatic Hearts directly, similar to how some quests provide guaranteed legendary items.
Trading Systems: While The Forge doesn’t currently have player trading, if it’s added in future updates, Prismatic Hearts would likely become valuable trade commodities.
New Boss Variants: Cave expansions might introduce new spider variants with different drop rates or guaranteed Prismatic Heart drops after certain achievements.
Troubleshooting Common Issues
Running into problems during your farming journey? Here are solutions to frequent issues:
Issue: “I can’t find the Spider Cave”
Solution: The Spider Cave entrance is on Frostspire Expanse’s southwest area. If you’ve completed any Raven quests, you’ve been there before. Look for the cave with ice formations around the entrance. Check your map or ask other players for directions.
Issue: “Prismarine Spider isn’t spawning”
Solution: The Prismarine Spider has a 2-5 minute respawn timer. If someone else just killed it, you’ll need to wait. In crowded public servers, consider server hopping to find one that just respawned. Private servers eliminate this issue entirely.
Issue: “I keep dying to the Prismarine Spider”
Solution: You’re either under-leveled or under-geared. Level up to 85+, craft better armor using Epic+ ores, bring more health potions, and learn the spider’s attack patterns. Don’t face-tank all damage—dodge and kite when necessary.
Issue: “I’ve killed 100+ spiders without a drop”
Solution: First, confirm you’re killing the Prismarine Spider (the large mini-boss) and not smaller spiders. Second, activate luck modifiers if you haven’t already. Third, RNG can be cruel—some players experience extremely bad luck streaks. Keep trying or return during a 2x Luck event.
Issue: “The cave is too dark to navigate”
Solution: Purchase the Simple Lantern from the Bard NPC for 350 gold. It’s a one-time purchase that permanently provides light in dark areas. This is essential for efficient cave navigation.
Frequently Asked Questions
How do you get the Prismatic Heart in The Forge?
The Prismatic Heart is obtained by defeating spider enemies in the Spider Cave located on Island 3 (Frostspire Expanse). Specifically, the Prismarine Spider mini-boss has the highest drop rate at approximately 1 in 15-50 kills with proper luck modifiers. You must be Level 70+ to access this island and should be Level 80+ for comfortable farming.
What is the drop rate for Prismatic Heart in The Forge?
The game displays a 1 in 33,333 drop rate, but actual testing reveals the Prismarine Spider has an approximate 1 in 15 to 1 in 50 drop rate depending on your luck modifiers. With maximum luck stacking (Luck Totems, Luck Potions, Angel race), players report rates as good as 1 in 8 to 1 in 15 kills. The displayed rate appears to be incorrect or applies only to weaker spider variants.
Where is the Spider Cave in The Forge?
The Spider Cave is located on Frostspire Expanse (Island 3) in the southwest area of the map. You need to reach Level 70 and have the Portal Tool unlocked to access this island. The cave entrance has ice formations surrounding it and is the same location visited during early Raven questline objectives.
What is the Prismatic Heart used for in The Forge?
The Prismatic Heart has three primary uses: (1) Completing Auron’s Cult Quest to unlock the Dragon Head Pickaxe, (2) Forging weapons and armor with a 5.5x multiplier plus passive traits including 20% Critical Chance and 5% Critical Damage, and (3) Selling for substantial gold at Greedy Cey’s shop, though this isn’t recommended until you have extras.
Can you get Prismatic Heart from Crystal Spiders?
Technically yes, but practically no. Crystal Spiders and Diamond Spiders can drop Prismatic Hearts, but their drop rates are much lower (closer to the actual 1 in 33,333 rate). The Prismarine Spider boss is the only efficient source for farming Prismatic Hearts, with a drop rate roughly 100x better than smaller spider variants.
How long does it take to get Prismatic Heart in The Forge?
With optimal conditions (private server, max luck modifiers, high level), you can obtain a Prismatic Heart in 20-45 minutes. Under average conditions (public server, some luck, adequate gear), expect 1-2 hours of farming. In challenging scenarios (crowded server, no luck modifiers, minimum level), it may take 2-4 hours or longer depending on RNG.
Is the Dragon Head Pickaxe worth getting in The Forge?
Absolutely yes. The Dragon Head Pickaxe is currently the strongest pickaxe in The Forge with 750 mining power, +15% mining speed, +78% luck boost, and 4 rune slots. It outperforms even the Prismatic Pickaxe and is designed for current and future end-game content. The investment of time farming three hearts (Prismatic, Yeti, Golem) plus 2,750,000 gold provides massive long-term mining efficiency gains.
Can Prismatic Hearts be traded in The Forge?
Currently, The Forge does not have a player trading system. Prismatic Hearts cannot be traded between players. However, if trading is added in future updates, legendary materials like Prismatic Hearts would likely be among the most valuable trade commodities in the game economy.
What’s the best race for farming Prismatic Hearts?
The Angel race (Mythical rarity) is optimal for farming Prismatic Hearts due to its +10% luck bonus—the highest in the game. However, since rerolling for Angel has a 0.1% chance, practical alternatives include Dwarf (Epic, +5% luck) or any race with luck bonuses. The luck difference between races is minimal compared to using Luck Potions and Luck Totems.
Do Luck Potions stack with other luck bonuses?
Yes! Luck Potions stack with all other luck sources including race bonuses, pickaxe luck stats, Luck Totems, and event-based luck multipliers like 2x Luck weekends. This multiplicative stacking is why maximizing luck through every available source dramatically improves your Prismatic Heart farming efficiency.
Conclusion
Obtaining the Prismatic Heart in The Forge might seem daunting with its legendary rarity status, but with the right approach, preparation, and persistence, it’s absolutely achievable for any dedicated player. The key is understanding that the displayed 1 in 33,333 rate is misleading—focusing on the Prismarine Spider boss with proper luck modifiers gives you realistic odds of success within 1-2 hours of farming.
Remember these essential takeaways as you begin your farming journey:
Preparation is Everything: Don’t attempt farming until you’re Level 80+ with decent equipment, plenty of health potions, and at least one luck modifier active.
Focus on Prismarine Spider: Ignore smaller spider variants and concentrate exclusively on the Prismarine Spider mini-boss for maximum efficiency.
Use Your First Heart Wisely: Always complete Auron’s Cult Quest with your first Prismatic Heart. The path to the Dragon Head Pickaxe provides far more long-term value than any alternative use.
Patience Wins: RNG can be frustrating, but persistence always pays off. Many players get their Prismatic Heart within their first hour of focused farming.
Optimize for Efficiency: Private servers, luck stacking, and combining with Raven Quest 2 can cut your farming time in half.
The Prismatic Heart represents a major milestone in your Forge progression, unlocking access to the game’s most powerful pickaxe and opening up new possibilities for crafting legendary equipment. Whether you’re a completionist hunting every legendary item or a pragmatist focused on efficient progression, obtaining this multicolored ore is a worthy goal that significantly enhances your gameplay experience.
Now that you’re equipped with comprehensive knowledge about Prismatic Heart farming, it’s time to venture into the Spider Cave and claim your legendary prize. May your luck be high, your swings be true, and your first Prismatic Heart drop quickly!
