What is the Infusion Altar?

The Infusion Altar is a revolutionary feature introduced in the Fisch Tidefall update that allows you to permanently modify and upgrade your fishing rod’s stats. Located in the Sunken Reliquary, this mystical altar summons Mella, a powerful mermaid who can enhance your rods beyond their normal capabilities. Unlike temporary enchantments, these upgrades are permanent and can significantly boost your fishing performance.

The altar requires three special essences to activate: Requis, Tide, and Thalass Essence. Each essence has unique acquisition methods, making the journey to rod enhancement an adventure in itself. Once you’ve gathered all three, Mella will appear and offer you the chance to upgrade any rod in your inventory.

Step 1: Accessing Tidefall

Before you can even think about using the Infusion Altar, you need to reach the Tidefall area. This underwater paradise is hidden deep beneath the ocean surface and requires special equipment to survive the intense pressure.

Required Equipment

Advanced Diving Gear (15,000 C$)

Purchase from the Buoy behind Sunstone at coordinates (-790, 125, -3100)
Provides extended oxygen supply and basic pressure protection

Tidebreaker (40,000 C$)

Buy from Desolate Deep
Essential for withstanding the extreme pressure in deeper waters

Alternative: Water Bubble

If you prefer not to buy the Advanced Diving Gear
Can be used as a substitute for oxygen management

The Journey to Underwater Opening

Spawn a boat at Moosewood Village shores
Head toward Ancient Isle direction
Look for Diver Boats parked in the middle of the Ocean
Find the Red Diver Boat – this is your key to Tidefall access
Talk to the left NPC and select “I’ll look for him” to start the Lost Diver quest

Completing the Lost Diver Quest

This quest is mandatory for Tidefall access and rewards you with the crucial Abyssal Tonic:

Equip your gear: Super Flippers, Tidebreaker, and Advanced Diving Gear
Jump into the ocean and watch for the purple pressure bar
Navigate deeper past two bridge-like obstacles
Find the sunken submarine with the Lost Diver on its right side
Rescue the diver and return to the surface
Receive Abyssal Tonic – this item is essential for surviving Tidefall’s pressure

Pro Tip: If your purple pressure bar depletes, you’ll be eliminated instantly, even with oxygen remaining. Always keep an eye on both bars!

Step-by-Step Guide:

Locate the Magical Diver in Sunken Reliquary

Catch an Omnithal – rare fish, check our Omnithal catching guide
Return to Magical Diver with both fish

Pro Tip: Omnithal is quite rare – consider using high-luck rods and bait to increase your chances.

Tide and Thalass Essence – Dripstone Mining

These two essences are obtained through the same method: mining Dripstones during the Dripstone Collapse event.

Understanding Dripstone Collapse Events:

Natural Spawning: Random occurrence throughout the day
Manual Triggering: Use Dripstone Collapse Totem
Duration: Limited time window per event
Locations: Anywhere in Tidefall sublocations

Required Tools:

Pickaxe (5,000 C$ from Northern Expedition entrance)
Patience – drop rates are not guaranteed

Event Triggering Methods:

Method 1: Natural Events

Wait for random Dripstone Collapse announcements
Free but unpredictable
May take several hours

Method 2: Dripstone Collapse Totem

Price: 7.5M C$ (Tidefall area) or 35M C$ (other reports)
Location: Near the Fallen Rod in Tidefall central area
Benefit: Instant event trigger on demand
Recommendation: Worth the investment for serious players

Mining Process:

Wait for event announcement or use totem
Locate Dripstones – sharp, pointy stones appearing during event
Equip your pickaxe – essential for mining
Mine the Dripstone 3-4 times
Collect rewards: Either Tide Essence, Thalass Essence, or regular stone
Repeat until you have both essences

Essence Farming Strategy:

Explore all sublocations: Different areas may have better drop rates
Focus on high-traffic areas: Coral Bastion, Collapsed Ruins, Crowned Ruins
Use multiple pickaxes: Bring extras in case one breaks
Team up: Share totem costs with friends for economy

Drop Rate Tips:

No guaranteed drops: You might get stones instead of essences
Persistence is key: May need 10-20+ Dripstone mines per essence
Event timing: Each event spawns multiple Dripstones across the area
Location cycling: Move between sublocations during events

Step 4: Activating the Infusion Altar

Once you have all three essences, it’s time to activate the altar and meet Mella!

Altar Location: Sunken Reliquary GPS Coordinates: (2939.6, -1102.8, -90.7)

Activation Process:

Navigate to Sunken Reliquary – one of the four branch sublocations
Find the Infusion Altar at the end of the large hallway
Place essences one by one in the altar slots
Watch the summoning animation as Mella appears
Speak with Mella to begin the upgrade process

Step 5: Upgrading Your Rod with Mella

Mella offers permanent stat upgrades for any rod in your inventory. Here’s what you need to know:

Available Upgrades:

Passive Luck: Increased catch rates
Lure Speed: Faster fish attraction
Control: Better reeling control (Note: Some reports say this isn’t upgraded)

Other base stats: Various improvements depending on rod

Upgrade Process:
