All Star Tower Defense X tier list is the most reliable reference for building a strong team in every game mode. With new banners and balancing updates, knowing each unit’s true strength, role, and best Traits will help you summon, upgrade, and reroll for optimal results.
S-Tier Units – The Current Meta Powerhouses
S-tier units are the strongest, most meta-defining choices in ASTDX. These are ideal for Infinite Mode, Story Mode, and leaderboard pushing due to their exceptional DPS, range, utility, and synergy with Traits. Most S-tier units are expensive to upgrade, but their impact is unmatched.
| Unit | Key Strengths | Weaknesses | Best Traits |
|---|---|---|---|
| Slayer Mage | Massive AoE, very high DPS, Infinite meta | Slow SPA, costly upgrades | All Star, Genesis, Bloodlust |
| Xero | Best area buff, strong team support | Minimal DPS, expensive | All Star, Corrupted, Genesis |
| The Strongest One | Insane DPS & range, ultimate boss killer | Extremely costly to max | All Star, Bloodlust, Genesis |
| King Kaoe | +75% damage buff to team, shield break | No direct DPS | Sharpshooter, Companion |
| Dark Wing | Superb range, strong DPS, hybrid utility | Expensive placement/upgrades | All Star, Genesis, Bloodlust |
| Venus | Huge AoE, top DPS, farthest range | Long SPA, expensive | All Star, Genesis, Bloodlust |
| Airren | Single-target DPS, strong summons | Costly to use/upgrade | All Star, Bloodlust, Genesis |
| Mysterious X | Team stun, decent DPS, utility | Shorter range, pricey | All Star, Corrupted, Genesis |
| Zorro | High AoE and DPS, far range | Slower SPA, costly | All Star, Corrupted, Genesis |
| Explosion Artist | Large range, good DPS | Pricey, slow SPA | All Star, Corrupted, Genesis |
Why S-tier?
These units are meta for both late-game Infinite and Story Mode. Their abilities (buffs, AoE, stuns, or insane DPS) make them invaluable for high-level play. Focus your Gems and upgrades on these as much as possible.
A-Tier Units – Excellent and Flexible Choices
A-tier units are very powerful, useful in nearly all modes, and are often stepping stones before you get full S-tier rosters. They offer good DPS, special effects (freeze, burn, bleed), or strong single-target utility.
| Unit | Key Strengths | Weaknesses | Best Traits |
|---|---|---|---|
| Yuni | High DPS, fast SPA, great single target | Range a bit short, costly | All Star, Bloodlust, Genesis |
| Kosuke (TS) | Long range, reliable DPS, best 4-star | SPA a bit slow, not S-tier DPS | Bloodlust, Genesis, Sharpshooter |
| Borul | Strong range/DPS, 4-star meta | Expensive to upgrade | Sharpshooter, Zenkai III, Dexterity III |
| Janji | Burn over time, AoE utility | Very slow SPA | Sharpshooter, Dexterity III, Zenkai III |
| Ikki (Slayer) | Balanced DPS/range, easy to get | Slow SPA | Sharpshooter, Zenkai III, Dexterity III |
| Shirtless Magician | Freeze effect, great for control | Lower DPS, mid SPA | Sharpshooter, Dexterity III, Zenkai III |
| Dual Servant | High single-target DPS | Slow SPA | Sharpshooter, Zenkai III, Dexterity III |
| Stampede | Strong range, decent DPS | Long SPA, small AoE | Sharpshooter, Zenkai III, Dexterity III |
| Zaruto (Sage) | Decent DPS, starter-friendly | Slow SPA | Sharpshooter, Zenkai III, Dexterity III |
| Ice Queen | Freeze, good range | Weak DPS, long SPA | Sharpshooter, Dexterity III, Zenkai III |
| Humble-Swordman (Selection) | Bleed, solid DPS | Very slow SPA | Sharpshooter, Dexterity III, Zenkai III |
Why A-tier?
They’re strong, easy to use, and usually easier to obtain or upgrade than S-tier. Great for new to mid-level players or as support units in meta teams.
B-Tier Units – Solid but Outclassed
B-tier units are reliable in early or mid-game, with some farming or utility use, but eventually get outperformed by higher tiers.
| Unit | Key Strengths | Weaknesses | Best Traits |
|---|---|---|---|
| Ramen Grill Master | Cash farming each turn | Weak late game, needs Awaken | Midas, Companion |
| Nezichi | Strong single-target DPS | Short range/AoE | Zenkai III, Dexterity III |
| Koro (Lobby) | Fast SPA, full AoE | Low DPS, short range | Zenkai III, Dexterity III |
| The Cursed One | Good DPS, bonus damage | Short range, small AoE | Zenkai III, Dexterity III |
| Uru | Good range, fast SPA | Low base damage | Sharpshooter, Zenkai III, Dexterity III |
| Vegu | Best 3-star, strong DPS/range | Hill-only placement | Sharpshooter, Zenkai III, Dexterity III |
| Kosuke | Range, stun, DOT | Lower total DPS | Sharpshooter, Dexterity III, Zenkai III |
| Koku | Good range, OK DPS | Very slow SPA | Sharpshooter, Dexterity III, Zenkai III |
Why B-tier?
Decent for casual play or starting out, but should be replaced as soon as A/S-tier units are available.
C-Tier Units – For Starters or Emergency
C-tier units are generally used as temporary solutions when you have no better choices.
| Unit | Key Strengths | Weaknesses | Best Traits |
|---|---|---|---|
| Captain | Burn, decent DPS/range | Slow SPA | Sharpshooter, Dexterity III, Zenkai III |
| Ruffy | Good range, solid DPS | Hill-only placement | Sharpshooter, Dexterity III, Zenkai III |
| Humble-Swordman | High DPS, OK SPA | Very short range | Zenkai III, Dexterity III |
| Jon Jo | High single-target DPS | Very short range | Zenkai III, Dexterity III |
| Anti Magician | Decent DPS/range | Outclassed by higher tiers | Zenkai III, Dexterity III |
Why C-tier?
Best for the first few levels or if you lack higher-tier pulls, but not suitable for meta play.
D-Tier Units – Least Recommended
D-tier units are weak, used only as placeholders if nothing else is available.
| Unit | Key Strengths | Weaknesses | Best Traits |
|---|---|---|---|
| Spirit Detective | OK DPS and range | Weak overall | Zenkai III, Dexterity III |
| Koro | Good SPA | Low DPS, short range | Zenkai III, Dexterity III |
| Zaruto | Decent DPS | Poor range, mid quality | Zenkai III, Dexterity III |
How to Summon, Upgrade, and Reroll in ASTDX
Summon with Gems: Units are summoned from Banner X and Y, rotating every 60 minutes. Only summon when your target unit appears.
Capsule System: For unique units not in the current banner.
Level Up Units: Use XP, unlock Hidden Potential at level 18 for a major boost.
Reroll Traits: Crucial for maximizing stats. Always aim for recommended traits for each unit.
Upgrade Path: Prioritize S-tier, then A-tier. Use B, C, D-tiers only as needed.

Don’t waste too many Gems on banners without your target.
Rotate units as you get stronger pulls, always aiming to upgrade your overall team quality.
