How to Solo Esdeath Trial in ASTD X (All Star Tower Defense X)
Taking on the Esdeath Trial solo in ASTD X isn’t for the faint of heart. With tight mechanics, randomized stuns, and overwhelming waves, it’s a challenge even for experienced players. But if you’re equipped with the right units and strategy, soloing it is absolutely possible. This guide breaks down everything you need to succeed in the Esdeath Trial, including the best team comp, traits, and strategy.
Best Team to Solo Esdeath Trial

Your solo lineup will focus on one strong DPS and a full supporting cast. Here’s the recommended team setup:
DPS Unit: Ulquiora
- This is your only main damage dealer. Without him, this strategy falls apart.
Buff Unit: Erwin
- Used to destroy shields and provide massive attack buffs to Ulquiora.
Slow Unit: Blackbeard
- Crucial for slowing down the boss and enemy waves.
Freeze Unit: Gray
- Helps control enemies and reduce pressure during intense stuns.
Money Farm Unit: Ramen Guy
- Essential for funding your entire setup.
Note: These units are pretty much required. There may be room to swap in alternatives, but only if they serve the same purpose with equal or better performance.
Ulquiora Build & Trait Suggestions

Ulquiora is the core of your damage output, so investing in the right build is important. Here’s what works:
Trait Recommendation:
- Genesis: Highly recommended for maximizing raw damage.
- Bloodlust or Corruption might also work depending on your playstyle.
- Avoid All-Star trait – the trial has too many enemies and the effect won’t hold up.
Skill Tree Setup:
- Prioritize Damage nodes
- Stack Double Crit nodes if possible.
- Avoid gimmicky or untested paths; stay safe with reliable damage boosts.
Strategy & Walkthrough

- Start with Ramen Guy: Get your money flow going early.
- Place Ulquiora ASAP: Start racking up damage the moment you can afford him.
- Blackbeard Setup: Position for optimal slow coverage to manage waves.
- Use Erwin Wisely: Don’t just buff constantly — time your Erwin buffs for shield-heavy waves and boss phases.
- Gray Placement: Use freezing to delay large groups and buy time when stuns become overwhelming.
- Expect RNG: Some runs will fail due to bad stun patterns from Esdeath. Don’t get discouraged — retry and adjust.
What Makes This Trial Hard?
- Multiple Bosses: While it’s technically one Esdeath, the trial mechanics cycle through phases like fighting three different bosses.
- Constant Stuns: The stun effects are brutal and unpredictable, making RNG a real factor.
- Shield Waves: Erwin is necessary to break through these or your damage will stall.
Soloing the Esdeath Trial in ASTD X requires planning, the right team, and a bit of luck. Focus on making Ulquiora as strong as possible, and let your support units handle everything else. Be prepared to fail a few times, but once you get that winning run, it’ll be well worth it. Good luck, and may your stuns go easy on you.
