How to Get Unbound Esdeath (Etri) in All Star Tower Defense X?

Method 1: Grinding Through Trials

The first method to obtain Etri requires dedication and a bit of luck. Here’s everything you need to know about the Trials approach:

Level Requirement: You must reach Level 25 before accessing Trials mode. If you’re not there yet, focus on completing story missions and daily challenges to level up quickly. Check out our ASTD X codes guide for free gems to help with progression.

Drop Rates:

  • Regular Difficulty: 1% chance
  • Strategist Difficulty: 10% chance

I strongly recommend playing on Strategist difficulty despite the increased challenge. The 10x better drop rate makes it worth investing in a strong team composition. Based on community reports, most players obtain Etri within 15-25 Strategist runs, though RNG can be cruel.

Best Teams for Trials: To consistently clear Strategist difficulty, you’ll want units from the top tiers of the ASTD X tier list. Focus on:

  • Dark Wing for massive DPS
  • The Strongest One for boss elimination
  • Ramen Grill Master for economy
  • A solid support unit with buffs

Method 2: Star Scroll Purchase (Guaranteed Method)

If grinding isn’t your style or luck isn’t on your side, the Star Scroll offers a guaranteed path to Etri:

  1. Navigate to Trial Shop: Located in the main lobby, look for the shop icon
  2. Purchase Star Scroll (Etri): Costs 250 Trial Shop Tokens
  3. Open Items Tab: Access your inventory from the main menu
  4. Select Star Scroll (Etri): Find it among your items
  5. Click “Use”: Instantly receive Unbound Etri

Earning Trial Tokens Fast:

  • Complete daily Trial runs (even on Regular difficulty)
  • Participate in special events offering bonus tokens
  • Trade duplicate Trial rewards for tokens
  • Join the official ASTD Discord for token-earning events

How to Ascend Unbound Esdeath in Roblox ASTD X?

Ascending Etri transforms her from a good unit into an absolute powerhouse. The process requires specific materials and meeting certain conditions.

Material Farming Guide

Etri’s Rapier (Fastest Method)

Since Strategist difficulty guarantees a 100% drop rate, this is your most efficient farming route:

  • Average time per run: 8-10 minutes
  • Total runs needed: 10
  • Estimated farming time: 1.5-2 hours

Pro tip: Use the AFK farming method to make this process less tedious.

EXP IV Crafting Process

This is often the bottleneck for new players. Here’s the exact crafting chain:

  1. Farm EXP I & II: Play Infinite Mode waves 30-50
  2. Combine for EXP III: 3x EXP I → 1x EXP II, 3x EXP II → 1x EXP III
  3. Create EXP IV: 3x EXP III → 1x EXP IV

Total materials needed for 5x EXP IV:

  • 135x EXP I (base requirement)
  • Approximately 3-4 hours of focused Infinite Mode farming

For detailed EXP farming strategies, check our Ghost III & EXP IV farming guide.

Ghost Materials Strategy

Ghost I (Blue):

  • Play Daily Challenge, Future City, or Hidden Storm Village on Hard
  • Ghost Eggs have ~40% drop rate
  • Transform eggs in Items tab (1:1 conversion)

Ghost III (Rainbow): The rarest ascension material requires patience:

  • Expert Challenge modes: 30% drop rate
  • Alternative: Combine lower tier Ghost materials
  • Best farming day: Check daily rotation for 100% Ghost drop events

Ascension Process

Once you’ve gathered all materials:

  1. Open Units Tab: From the main menu
  2. Select Etri: Find her in your unit collection
  3. Check Requirements: Ensure you have 500+ eliminations
  4. Click the 7,500 Gold Button: There’s no separate “Ascend” button
  5. Confirm Ascension: Your materials will be consumed

Important: The ascension button appears as the gold cost, not a traditional “Ascend” button – many players miss this!

Etri’s Abilities and Why She’s Worth It in 2026?

Base Abilities

  • Primary Attack: Ice-based projectiles with slowing effect
  • Range: Above-average for Unbound units
  • DPS: Consistently high against both ground and air units

Special Ability: Mokahadoma

  • Effect: Freezes ALL enemies in range for 4 seconds
  • Cooldown: 40 seconds
  • Hidden Mechanic: 6-second immunity window prevents stun-locking

This ability makes Etri invaluable for:

  • Infinite Mode high waves
  • Story Mode boss rushes
  • Ranked PvP defense strategies

Post-Ascension Improvements

Ascending Etri provides:

  • 30% increased base damage
  • Extended freeze duration (4→5 seconds)
  • Reduced ability cooldown (40→35 seconds)
  • Hidden upgrade: Pierce effect on frozen enemies

Optimal Etri Builds and Team Compositions

Best Trait Combinations

According to the ASTD X traits tier list, prioritize:

  1. All Star (0.2% rate): 300% damage boost – absolutely broken on Etri
  2. Genesis: Excellent for wave clear
  3. Bloodlust: Synergizes with her freeze for elimination stacking

Skill Tree Path

When using the skill tree system:

  • Recommended: Range path for maximum freeze coverage
  • Alternative: Damage path if you have All Star trait

Team Synergies

Etri works exceptionally well with:

  • Time-manipulation units: Stack crowd control
  • AoE damage dealers: Capitalize on frozen groups
  • Economy units: Her control buys time for farming

Common Mistakes to Avoid

  1. Wrong Ascension Button: Remember, it’s the gold cost button, not a separate “Ascend” option
  2. Insufficient Eliminations: Track your kills – 500 is required BEFORE ascension
  3. Material Confusion: Ghost I comes in different colors – you need specifically BLUE
  4. Skipping Strategist: The 10% drop rate is worth the challenge
  5. Hoarding Materials: Ascend immediately – the power spike helps farm faster

Advanced Tips and Strategies

Infinite Mode Positioning

Place Etri at choke points where paths converge. Her freeze ability shines when affecting multiple lanes simultaneously. I’ve reached wave 100+ using this strategy.

PvP Defense Setup

In ranked matches, hide Etri behind tankier units. Opponents often underestimate her until the freeze locks down their entire push.

Material Efficiency

Start farming Ghost materials while grinding for Etri. By the time you obtain her, you’ll have most ascension requirements ready.

For players with OG rewards, Etri pairs exceptionally well with legacy units.

Frequently Asked Questions

Is Unbound Esdeath worth 250 Trial Tokens?

Absolutely. Etri remains meta-relevant even months after release. The time saved versus grinding makes the token cost worthwhile, especially for players focused on competitive modes.

What’s the average time to get Etri through Trials?

Playing Strategist difficulty with a 10% drop rate, expect 10-15 runs on average. That’s roughly 2-3 hours of active gameplay, though RNG varies wildly.

Can I trade for Unbound Esdeath?

Currently, trading is disabled in ASTD X. When it launches, Etri will likely be a high-value trade unit.

Yes, she excels in Story, Infinite, Challenges, and PvP. Her versatility makes her a safe investment for any player.

Should I use skill orbs on Etri?

Definitely. As a meta unit, investing skill orbs provides long-term value. Focus on the range path unless you have exceptional traits.

What happens if I don’t have 500 eliminations?

The ascension button won’t appear. Place Etri in your team and farm easy Story Mode stages until you reach the requirement.

Is there a faster way to get Ghost III (Rainbow)?

Check the daily Challenge rotation. Some days offer 100% drop rates for Ghost materials. Plan your farming accordingly.
