Introduction

Traits are powerful modifiers rolled onto units that can dramatically change how strong they are. You obtain traits at the Robot in the lobby or from your inventory, and you reroll unwanted traits using Trait Burners. The All Star trait is the S-tier prize — it grants a massive damage boost and is one of the best rolls in the game. Other traits improve damage, attack speed, survivability or critical hit chance. Trait chances and buff values are listed in the in-game Index, so you can check the exact odds before spending Burners. Traits apply in all modes except PvP, Classic Infinite and Strategist Trials. Because traits multiply a unit's effectiveness, a good trait can make a mid-tier unit outperform an S-tier unit with a bad roll. This guide covers the trait list, the reroll system and the best traits to chase.

Top Trait Profiles

S

All Star

legendary

The S-tier damage king — one of the best rolls in the game

EffectGrants a massive damage boost that turns a good unit into a raid carry.
OddsLow — S-tier traits are the rarest rolls in the trait pool.
Best OnHigh-DPS carries and raid units that benefit most from the raw damage multiplier.
StrategySave Burners for your best unit and reroll until All Star lands — patience pays off.
A

Godly

epic

High-tier damage multiplier — a strong fallback

EffectAdds a substantial damage multiplier, slightly below All Star in raw output.
OddsBetter odds than S-tier, making it a realistic target for most players.
Best OnVersatile on any damage dealer when All Star is out of reach.
StrategyStop rerolling if Godly lands — it is strong enough for endgame content.
A

Swift

epic

Attack speed boost that ramps damage over time

EffectIncreases attack speed so units output more damage per second across a wave.
OddsModerate — A-tier odds that make it a common strong roll.
Best OnFast-attacking units where the speed multiplier compounds existing DPS.
StrategyGreat for Infinite Mode where sustained DPS outvalues burst.
B

Vampiric

rare

Heal-on-kill survivability for long fights

EffectHeals the unit on kills, improving survival in long waves.
OddsCommon B-tier odds — easy to roll when needed.
Best OnFrontline melee and tanks that take damage while clearing waves.
StrategyUseful in Infinite Mode to keep your frontline alive without extra supports. On long fights it reduces the need for dedicated healers. Pair it with damage traits for a self-sustaining frontline carry.
B

Lucky

rare

Crit chance boost for burst damage

EffectBoosts critical hit chance for occasional high-damage burst.
OddsCommon B-tier odds — accessible for most players.
Best OnSingle-target carries where crits amplify boss damage.
StrategyPair with damage traits for a balanced damage profile on your main carry. Critical bursts are especially valuable against raid bosses. Combine Lucky with a damage trait for a balanced damage profile.

Core Mechanics

Traits are assigned when you obtain a unit, but you can reroll them. The reroll happens at the Robot in the lobby or directly from your inventory, and it costs Trait Burners. Each reroll randomly assigns a new trait from the pool, weighted by the trait's rarity — S-tier traits like All Star have lower odds than common ones. The in-game Index lists the exact trait chances and buff values, so you can plan how many Burners a good roll might take. Traits multiply a unit's effectiveness: a damage trait boosts output, a speed trait raises attack rate, and survivability traits keep units alive longer. Traits apply in most game modes but are disabled in PvP, Classic Infinite and Strategist Trials, so you still need strong base units for those modes. Rerolling strategy is about patience — burning all your Trait Burners on one unit can be wasteful if a better trait has low odds.

Advantages

Traits add a deep layer of character progression that rewards grinding and resource planning. A good trait can transform a mid-tier unit into a star, so your collection has hidden potential beyond the tier list. The reroll system with Trait Burners gives you control — you are not stuck with a bad roll forever. The S-tier All Star trait provides a massive damage boost that can define an endgame team. Because traits apply across most modes, a well-traited unit is valuable everywhere, and trait knowledge gives you a real edge over players who ignore the system. Trait rerolling also gives Trait Burners a purpose, making them a meaningful currency to earn and spend.

Challenges

Trait rerolling is a resource sink that can drain Trait Burners without a guaranteed result. S-tier traits have low odds, so chasing All Star can eat through your Burner supply. Traits are disabled in PvP, Classic Infinite and Strategist Trials, so a heavily trait-reliant team underperforms in those modes. The RNG element means two players with the same unit can have wildly different effective power based on trait luck. New players often waste Burners on low-value rerolls before learning the trait odds. Finally, trait value depends on the unit — a damage trait is wasted on a support unit, so you need to match traits to roles.

Frequently Asked Questions

What is the best trait in ASTD?+
The All Star trait is the best in the game — an S-tier roll that grants a massive damage boost. Other strong traits include Godly for raw damage, Swift for attack speed, and Vampiric for survivability. The best trait for you depends on your unit's role: damage dealers want All Star or Godly, while supports benefit from utility or survival traits.
How do I reroll a trait?+
You reroll traits at the Robot in the lobby or directly from your inventory. Each reroll costs Trait Burners and randomly assigns a new trait from the pool. S-tier traits have lower odds than common ones, so rerolling for All Star can take many Burners. Check the in-game Index for exact trait chances and buff values before spending.
How do I get Trait Burners?+
Trait Burners are earned from gameplay, events and shop purchases. They are the currency consumed by each trait reroll. Because good traits have low odds, you should save Burners for units that matter and avoid wasting them on low-value rerolls. Saving Trait Burners for your most important carries and matching trait type to unit role gets the best value from every reroll.
Do traits work in every game mode?+
No. Traits apply in most modes, but they are disabled in PvP, Classic Infinite and Strategist Trials. This means a team built around trait bonuses underperforms in those modes. Keep strong base units without relying solely on traits if you plan to play those modes seriously. Saving Trait Burners for your most important carries and matching trait type to unit role gets the best value from every reroll.

Quick Tips

💡

Save Trait Burners for your main carries. Rerolling a support unit's trait wastes Burners that could secure All Star on your highest-damage unit — match traits to the units that matter most. Matching the trait you chase to the unit's role — damage on carries, survival on tanks — multiplies the value of every Trait Burner you spend.

💡

Check the in-game Index before spending. Knowing the exact trait odds and buff values lets you budget Burners and decide when a good-enough roll is better than chasing a perfect one. Matching the trait you chase to the unit's role — damage on carries, survival on tanks — multiplies the value of every Trait Burner you spend.

💡

Do not rely on traits for PvP or Classic Infinite. Traits are disabled in those modes, so build a strong base team that performs without trait bonuses. Matching the trait you chase to the unit's role — damage on carries, survival on tanks — multiplies the value of every Trait Burner you spend.

💡

A damage trait is wasted on a support unit. Match trait type to unit role — damage carries want All Star or Godly, while tanks and supports prefer survival or utility buffs. Matching the trait you chase to the unit's role — damage on carries, survival on tanks — multiplies the value of every Trait Burner you spend.
