Top Tier List Units Analysis

Understanding why a unit is top-tier is crucial for team building. The best units typically excel in multiple areas. They offer massive damage, useful crowd control, or game-changing support abilities.

Michishibo is widely considered the best unit in the game. This Unbound rarity unit has the highest one-shot damage potential and applies powerful bleed damage over time. Its main drawback is an extremely low 0.01 percent chance from summons.

Spider Boss (Chrollo) is a meta ground unit that poisons enemies with a damage-over-time effect. It boasts a very good range and overall DPS. Its ability deals insane damage to enemy waves, making it a consistent top performer.

Magma Marine specializes in burn damage, making it exceptional for clearing waves. It has very high DPS and excellent range. However, it has a relatively slow attack speed and is expensive to upgrade fully.

Support units like Xero are essential for late-game content. Xero buffs the damage of nearby allies and is meta for all game modes. Be aware that it has virtually zero DPS itself and is expensive to place and upgrade.

How to Use the Tier List Effectively

A tier list is a great guide, but a smart strategy is what leads to victory. You must consider your available resources, current progression, and team synergy.

Balance your team composition. A successful team requires a mix of damage dealers and support units. Do not fill all your slots with only S-Tier DPS units. Include a support like King Kaoe, who can boost the damage of all nearby allies by 75 percent.

Consider unit placement and type. Hill units can hit both ground and air enemies, while ground units cannot hit air enemies. Placing a hill unit like Slayer Mage on elevated terrain is crucial for full map coverage. Furthermore, some units have full area of effect attacks, while others only attack in a line or cone.

Plan for the late game. Some units are fantastic for early and mid-game, but fall off later. Others, like Dark Wing, are expensive to place but become amazing wave-clearing specialists for the endgame. Always think about how a unit will perform in the most challenging Infinite Mode waves.

Common Mistakes to Avoid

Many players, especially beginners, make simple errors that hinder their progress. Avoiding these pitfalls will save you valuable gems and time.

Ignoring support units is a frequent mistake. While a high-damage unit is flashy, a good support can double your team’s overall damage. Units like Onwin summon mini-units and provide an attack boost to your entire team.

Upgrading the wrong units wastes limited resources. Focus your evolution materials and gems on S-Tier and A-Tier units. Do not heavily invest in C-Tier or D-Tier units, as they will quickly become obsolete.

Misunderstanding summoning rates leads to frustration. The best units are often the rarest. Unbound units have a mere 0.01 percent drop rate, and 5-star units have a 1 percent drop rate. Manage your expectations and save gems for banner events featuring top-tier units.

Final Recommendations

This ASTD X tier list is your roadmap to building a dominant team. Prioritize obtaining and upgrading S-Tier units like Michishibo and Spider Boss. Remember to balance your team with reliable support and always adapt your strategy to the game mode you are playing.
