All Star Tower Defense X Units Tier List (In-Depth Version)
To help you better understand the summary of our All Star Tower Defense X tier list above, we prepared this breakdown section. Below, you'll find explanations for the criteria we used to rank each unit. Further down is a list of all units in ASTD X, including their details (targeting type, element, rarity, passive abilities) and pros and cons, categorized by their ranking in the tier list.
ASTD X Tier List Ranking Factors Explained
- Stats (DPS, Range, SPA): Stats are the most important thing for every DPS unit in All Star Tower Defense X, and the higher they are overall, the better that unit is. For support/utility units, stats aren't as important as their abilities.
- Targeting and Attack Type: Hill units can attack flying enemies, which you'll need for some maps. Also, Hill units have limited placement options, which can hinder their uptime and total DPS. The type of the unit's attack (Full AoE, Line, Cone, etc.) also affects the unit's ability to deal with multiple enemies.
- Passives and Abilities: Some units have strong passive or active abilities that increase their power substantially.
- Utility and CC: Support units are invaluable in ASTD X as they can generate money, CC enemies, buff your other units, and provide other forms of value. It's important to have a few in your team.
- Evolution Potential: Some lower-rarity units can evolve into higher-rarity ones, making them extra worth getting.
- Element: The unit's element affects which enemies are going to take increased or lowered damage from the unit's attacks. This is especially important for exclusive game modes.
- Teaming: Some units can combine with others and make a stronger unit. These units are especially good if you still don't have ascended 5★ units to fill out your squad.
