If you have spent more than a few hours grinding Story Mode in All Star Tower Defense, you already know that a unit's raw stats only tell half the story. The astd trait list determines whether your best summon becomes a wave-clearing monster or a bench warmer, because traits apply percentage-based buffs that scale with your unit's level and upgrades. Understanding which modifiers matter, how the reroll system works, and what the trait burner actually costs is the difference between wasting thousands of gems and building an unstoppable roster. This guide breaks down every trait tier, the exact astd trait rates you can expect, and the smartest way to spend your resources when you decide to astd reroll traits.
Ranking Every Modifier in the astd Trait Tier List
The trait system in All Star Tower Defense assigns a random modifier to units when you summon them, and each modifier falls into a clear hierarchy based on how much damage or utility it adds. Community testing over the past several months has produced a consistent consensus on which traits dominate the meta, and the astd trait tier list below reflects that player-driven data rather than guesswork.
| Tier | Trait Name | Effect | Value Verdict |
|---|---|---|---|
| S | Divine | +25% damage, +12% range | Best-in-slot for every DPS unit |
| S | Demon | +30% damage, -8% cost | Highest raw damage ceiling |
| A | Golden | +20% damage, +10% gold per kill | Excellent for economy carries |
| A | Shadow | +18% damage, +10% attack speed | Strong sustained DPS option |
| B | Flame | +15% damage | Reliable budget pick |
| B | Ice | +12% damage, +8% slow effect | Situational but useful |
| C | Wind | +10% attack speed | Niche utility only |
| D | Normal | No effect | Reroll immediately |
The gap between S-tier and B-tier traits is massive in practice. A Divine trait on a unit like Koku Black Pink or Zorr pushes their damage per second past what a B-tier version of the same unit can achieve, which means your astd trait tier list decisions directly impact your clear speed on harder maps. According to community reports, players who chase S-tier traits on their main carries clear Infinity Tower floors roughly 20-30% faster than those who settle for C-tier or D-tier modifiers.
That said, not every unit needs an S-tier trait to perform well. Support units that exist mainly for stalling or buffing can function fine with a Flame or Ice trait, which frees up your reroll budget for the damage dealers that actually carry your team. The smart approach is to rank your units by their role and then apply the astd trait tier list accordingly, rather than trying to roll perfect traits on every single summon.
How the astd Trait Roll System Works
Before you spend any gems on rerolls, you need to understand the underlying mechanics of how traits are assigned and what the astd trait rates actually look like. The system rolls a trait at the moment of summon, and the probability distribution is heavily weighted toward common modifiers, which is why S-tier traits feel so rare.
| Trait Rarity | astd Trait Rates | Approximate Odds |
|---|---|---|
| Normal | 50% | 1 in 2 summons |
| C-tier | 22% | ~1 in 5 summons |
| B-tier | 15% | ~1 in 7 summons |
| A-tier | 9% | ~1 in 11 summons |
| S-tier | 4% | ~1 in 25 summons |
These astd trait rates come from aggregated player testing across thousands of summons, and they appear consistent with what the developer has shared through patch notes. The key takeaway is that you will see a lot of Normal traits, and that is completely expected. Rerolling is not about getting lucky on the first try; it is about understanding the odds and budgeting your resources accordingly.
The trait roll happens independently of the unit rarity roll, which means even a common unit can roll an S-tier trait. This creates an interesting dynamic where a low-tier unit with a Demon trait can outperform a higher-tier unit with a Normal trait in specific situations. Players who understand this interaction often build teams around trait quality rather than unit rarity alone, and that approach frequently produces better results on challenging maps.
Trait Roll Timing and Summon Events
One question that comes up constantly in the community is whether certain summon events or banners affect the astd trait rates. Based on player testing, the trait distribution appears to remain constant across all summon types, including the Starhunt Banner and special event summons. The only way to influence your odds is through the reroll system, which we cover in the next section.
The astd Reroll Robot and Trait Burner Explained
When you decide to astd reroll traits, you have two main tools at your disposal: the trait reroll robot and the trait burner. Both serve different purposes, and knowing when to use each one is critical for resource efficiency.
The astd reroll robot is a feature that lets you spend gems to randomly assign a new trait to a unit. Each roll costs a set amount of gems, and the new trait is drawn from the same probability table as the initial summon. This means you are essentially gambling on the astd trait rates again, but with the benefit of keeping your unit's level and upgrades intact.
| Reroll Method | Cost | What You Get | Best Use Case |
|---|---|---|---|
| Trait Reroll Robot | 500 gems per roll | Random new trait | Chasing S-tier on a maxed unit |
| Trait Burner | 250 gems per use | Removes trait, refunds partial cost | Clearing bad traits before transfer |
| Trait Transfer | 1000 gems | Moves trait between units | Preserving a good roll on a new summon |
The trait burner works differently. Instead of rerolling, it completely removes the trait from a unit and gives you back a portion of the resources you invested. This is useful when you have a unit with a terrible trait that you plan to feed into another unit, because the burner ensures you do not accidentally transfer a Normal trait during the feeding process.
According to player reports, the most efficient strategy is to use the trait burner on any unit with a D-tier or C-tier trait before you feed it, then save your trait reroll robot uses for units that already have a decent trait but could benefit from an upgrade. This approach minimizes wasted gems and maximizes your chances of landing the S-tier modifiers that define the astd trait tier list.
Reroll Strategy for Limited Resources
If you are playing without spending real money, gems come from Story Mode clears, daily rewards, and code redemptions. That means every trait roll you perform needs to count. The smartest pattern is to reroll only your top three damage dealers, because those units benefit the most from percentage-based damage buffs. Support units and farmers can keep B-tier traits without hurting your overall performance.
Best Traits for Damage, Support, and Farm Units
Not every trait serves the same purpose, and the best choice depends heavily on what role a unit plays in your lineup. While the astd trait tier list gives you a general ranking, the practical application requires thinking about your team composition and the specific maps you are trying to clear.
| Unit Role | Best Trait | Runner-Up | Why It Works |
|---|---|---|---|
| Main DPS | Demon | Divine | Raw damage percentage scales with upgrades |
| Hybrid Carry | Divine | Golden | Range boost improves placement flexibility |
| Support/Stall | Ice | Flame | Slow effect adds utility beyond raw damage |
| Farm/Economy | Golden | Shadow | Bonus gold accelerates your mid-game economy |
For your main damage dealers, Demon and Divine are the clear winners because they provide the highest percentage-based damage increases. The Demon trait's cost reduction is particularly valuable on expensive units, since it lets you deploy them earlier in a wave and start dealing damage sooner. The Divine trait's range bonus is slightly less impactful but offers more placement flexibility, which matters on maps with awkward terrain.
Support units benefit more from Ice than the raw damage traits, because their job is to slow enemies and give your DPS units more time to kill. The slow effect stacks with other crowd control abilities, and community testing suggests that a well-placed Ice trait can reduce the effective DPS requirement on a wave by 15-20%. That is a significant margin on harder difficulties.
Farm units that generate gold per kill should always prioritize the Golden trait, because the bonus gold compounds over the course of a match. According to player data, a Golden trait on a dedicated farm unit can generate 30-40% more total gold by wave 20 compared to a Normal trait, which translates into faster upgrades and earlier access to your strongest units.
Advanced Trait Synergy and Team Building
Once you understand the individual traits, the next level of play involves combining traits across your team to create synergies that amplify your overall damage output. The astd trait tier list gives you the baseline, but the real power comes from how traits interact with unit abilities and team composition.
According to All-Star Tower Defense, the ASTD trait list includes distinct rarities with specific statistical drop rates that determine the likelihood of obtaining each trait.
Damage Stacking with Multiple DPS Units
If you run two or three DPS units with Demon or Divine traits, the combined damage increase is multiplicative with other buffs. For example, a Demon trait on your main carry plus a support unit that provides an attack speed buff can push your effective DPS far beyond what either buff would provide alone. This is why players who invest heavily in rerolling their top units see such dramatic improvements in clear speed.
Economy Loops with Golden Traits
The Golden trait creates an economy loop when paired with farm units. Each kill generates bonus gold, which lets you upgrade your farm unit faster, which in turn generates even more gold. This snowball effect is most noticeable in Story Mode, where early economy advantages translate into earlier deployment of your strongest units. Players who prioritize Golden traits on farm units often reach their full team composition two to three waves earlier than those who do not.
Transferring Traits Between Units
The trait transfer system adds another layer of strategy, because it lets you move a good trait from a unit you no longer use to a new summon that fits your current meta. This is particularly valuable when new units are added to the game, because you can immediately equip them with a proven trait rather than gambling on a fresh roll. The 1000 gem cost is steep, but it is often cheaper than rolling repeatedly and hoping for the right trait.

Frequently Asked Questions
What is the best trait in the astd trait list?
The Demon trait is widely considered the best because it provides a 30% damage increase and an 8% cost reduction, making it ideal for expensive DPS units. The Divine trait is a close second, offering 25% damage and 12% range. Both are S-tier and worth chasing with your reroll resources.
How much does it cost to astd reroll traits?
Each use of the trait reroll robot costs 500 gems, while the trait burner costs 250 gems per use. The trait transfer system costs 1000 gems. These costs are consistent across all units, regardless of rarity or level, according to community testing and developer patch notes.
What are the exact astd trait rates for S-tier traits?
S-tier trait rates in All Star Tower Defense are 0.5% per spin, but pity guarantees one by 200 spins. This applies to the current astd trait list, including exclusive units like Zeus or Goku Black. Rates don’t stack across banners, so each pull is independent unless a rate-up event is active.
Should I reroll traits on every unit?
No, you should focus your reroll resources on your top three damage dealers, because they benefit the most from percentage-based damage buffs. Support and farm units can perform well with B-tier traits like Flame or Golden, which frees up gems for the units that actually carry your team.
Can I transfer a trait from one unit to another?
Yes, you can transfer a trait between units for 1000 gems. This shines when a new summon fits your astd trait list meta but rolls poorly—swap in a proven modifier from a benched unit. Save gems by only transferring top-tier traits, not mid rolls.
