What Determines Unit Ranking in ASTD X?

Before we jump into the full tier list, it’s important to understand the factors used to evaluate each unit:

• Stats – DPS, range, and SPA (seconds per attack) all impact a unit’s raw power.
• Attack Type – AoE coverage (line, full, cone) and targeting style matter a lot, especially on larger maps.
• Abilities & Passives – Units with effects like stun, burn, bleed, or buffs can add extra value to your team.
• Utility & CC – Some units excel not in damage but in support roles like farming, buffing, or crowd control.
• Evolution & Teaming – Units that evolve or become stronger when paired with specific characters are often more viable.
• Element Matchups – Element types can affect enemy interactions in certain modes.

If you’re just getting started with All Star Tower Defense X, focus on unlocking units from the S+ and S tiers first. They offer the best return for your grind and will carry you through most of the content. Keep in mind that some 4-Star units become powerful when teamed with others, but if you’re not using their specific combos, they won’t be much help. Always aim to evolve and ascend your units when possible to unlock their full potential. This tier list will continue to evolve as new updates roll out, so be sure to revisit often and adjust your strategy accordingly.
