Trait buffs in All Star Tower Defense determine whether a unit carries your run or sits on the bench, yet most players never look past the glowing border color when rolling. The difference between a mythical trait and a common one is often a 2x damage gap, which translates to thousands of lost DPS across a full Story Mode clear. Because ASTD traits are permanent until you reroll or transfer them, understanding exactly what each buff does before spending gems saves you from wasting resources on effects that do not fit your unit's role.
The trait system sits at the heart of late-game progression, and knowing which astd damage trait pairs with a hybrid unit versus a pure nuker changes how you build your entire squad. This guide breaks down every buff value, explains how stacking works, and gives you a practical astd trait reroll guide so you can stop gambling blindly and start rolling with intent. By the time you finish reading, you will know precisely which traits deserve your gems and which ones you should burn without a second thought.
According to All-Star Tower Defense, trait buffs are applied as percentage-based multipliers to a unit's base stats, with the exact values varying per trait tier and unit rarity.
Understanding the ASTD Trait Buff System
Every unit in All Star Tower Defense rolls with a trait when summoned, and that trait modifies core combat stats through a system that works independently of star levels and upgrades. The buffs apply multiplicatively on top of your unit's base stats, which means a 30% damage increase from a trait combines with your upgrade path rather than replacing it. This is why a maxed unit with a strong trait can outperform a higher-star unit with a weak one, especially when you factor in the astd trait index that tracks all available effects.
The trait pool splits into several tiers, and each tier has a different chance of appearing when you roll. According to community data collected from thousands of summon sessions, the base rates favor common and uncommon traits heavily, while mythical trait rolls sit in the single digits. That rarity matters because the buff values scale dramatically with tier, so a mythical damage boost is roughly double what a common version provides.
| Trait Tier | Base Roll Rate | Damage Buff Range | Health Buff Range |
|---|---|---|---|
| Common | ~55% | 5% - 10% | 5% - 10% |
| Uncommon | ~25% | 10% - 15% | 10% - 15% |
| Rare | ~12% | 15% - 20% | 15% - 20% |
| Epic | ~6% | 20% - 30% | 20% - 30% |
| Mythical | ~2% | 30% - 50% | 30% - 50% |
The table above reflects the general pattern reported by players across multiple updates, though exact percentages shift slightly with each patch. What matters for your strategy is that trait buffs scale with tier, so chasing mythical rolls is not just about prestige—it is about getting the largest possible stat multiplier on your best units.
How Buffs Apply to Unit Stats
When a trait grants a damage buff, it modifies the unit's attack stat directly before any in-battle multipliers are calculated. That means a mythical trait with a 40% damage increase makes your unit hit 40% harder at every star level and every upgrade tier. The buff also applies to abilities and special attacks, which is why certain traits completely transform units that rely on their ultimate skills for burst damage.
Health buffs work the same way, increasing the effective HP pool that tanks and stall units rely on. Because the buffs are multiplicative with other sources of stat increases, stacking a damage trait with a high star level produces exponential returns rather than additive ones. This interaction is the core reason why the astd trait reroll guide community emphasizes saving your best traits for units you plan to max out completely.
For players aiming to maximize their damage output, understanding how to efficiently roll for these boosts is just as important as knowing which units to equip, so check out our guide on All Star Tower Defense How To Get Traits to save your gems.
Mythical Trait Values and Effects Breakdown
The mythical trait tier represents the pinnacle of the ASTD trait buffs system, offering the largest stat multipliers and the most impactful special effects. While lower tiers provide straightforward percentage boosts, mythical traits often come with additional mechanics that change how a unit performs in combat. Understanding these values helps you identify which mythical rolls are worth keeping and which ones you should reroll despite the rarity.
| Mythical Trait | Primary Buff | Secondary Effect | Best Unit Type |
|---|---|---|---|
| Divine Strength | +50% Damage | +15% Attack Speed | Pure DPS Nukers |
| Eternal Guard | +45% Health | +20% Defense | Tanks and Stalls |
| Swift Annihilation | +35% Damage | +25% Attack Speed | Hybrid Attackers |
| Arcane Mastery | +40% Damage | +10% Range | Long-Range Units |
| Unyielding Fortitude | +50% Health | +15% Damage Reduction | Frontline Defenders |
The table above shows the most commonly reported mythical trait configurations, though the exact values can vary slightly based on the roll. Players who track their summons report that Divine Strength and Swift Annihilation are the most sought-after for damage-focused teams, while Eternal Guard dominates tank builds. The secondary effects matter just as much as the primary buff because attack speed and range multiply your effective DPS in ways that raw damage alone cannot.
Comparing Damage Traits Across Tiers
When you look at astd damage trait options across all tiers, the gap between common and mythical becomes stark. A common damage trait might grant 8% extra damage, which barely moves the needle on a unit that already deals thousands of damage per hit. A mythical damage trait, by contrast, can push that same unit into one-shot territory against story mode enemies.
The practical implication is that you should prioritize rolling for damage traits on your main carries and accept lower-tier defensive traits on your tanks. This targeted approach to the astd trait reroll guide philosophy saves gems because you are not chasing mythical rolls on every single unit in your roster. Save your rerolls for the units that actually carry your damage output, and let your support units make do with whatever they rolled naturally.
How Trait Stacking and Transfer Work
Trait stacking in ASTD does not work the way many new players assume—you cannot stack multiple traits on a single unit to combine their buffs. Each unit holds exactly one trait, and that trait's effects apply in full without any way to add a second one. This limitation makes the astd transfer trait mechanic essential because it lets you move a valuable trait from a unit you no longer use to one that benefits more from the buff.
The transfer system requires a specific item that is consumed in the process, and the destination unit must not already have a trait equipped. According to player reports, the transfer item drops from certain game modes and can also be purchased with premium currency during limited-time events. Because transfers are one-way and consume the item, you want to be absolutely certain the destination unit is worth the investment before committing.
| Transfer Scenario | Recommended Action | Why It Matters |
|---|---|---|
| Mythical Damage Trait on Weak Unit | Transfer to Main Carry | Maximizes DPS output |
| Epic Health Trait on DPS Unit | Transfer to Tank | Better role alignment |
| Common Trait on Any Unit | Burn or Reroll | Not worth transfer cost |
| Mythical Speed Trait on Slow Unit | Transfer to Hybrid | Unlocks attack speed potential |
The astd transfer trait mechanic is particularly valuable when you pull a strong trait on a unit you only use for early-game farming. Moving that trait to your endgame carry saves you from rolling hundreds of times to get the same result, which is why experienced players hoard transfer items rather than spending them impulsively.
Stacking Rules and Multipliers
The multiplicative nature of trait buffs means they combine with other stat sources in a way that rewards focused investment. A unit with a mythical trait damage buff, max star level, and full upgrade path will deal significantly more damage than the sum of those individual bonuses would suggest. This compounding effect is why the community consistently ranks trait quality above almost every other factor when evaluating unit strength.
However, there are limits to what stacking can achieve. Trait buffs do not apply to global multipliers like team-wide damage boosts from other units, and some game modes apply their own stat caps that can reduce the effectiveness of high trait values. According to community testing, these caps rarely come into play during normal Story Mode progression, but they matter for Infinity Tower runs where enemy scaling outpaces your stat growth.
Practical Trait Reroll Strategy
A smart astd trait reroll guide approach starts with knowing when to reroll and when to accept what you have. The biggest mistake new players make is burning all their gems on rerolls for units that do not matter, leaving nothing for the carries that actually determine whether you clear difficult content. Prioritize your rerolls based on unit role and how much that unit contributes to your overall strategy.
Start by identifying your top three damage dealers and your main tank, then focus all reroll resources on those units. For damage dealers, you want any astd damage trait at epic or mythical tier, while tanks benefit most from health and defense buffs. If you pull a mythical trait that does not fit the unit's role, hold onto it and use the astd transfer trait mechanic to move it to a better candidate.
-
Save rerolls for carries — your main DPS units deserve the best traits
-
Accept good epic rolls — not every unit needs a mythical trait to perform
-
Transfer before rerolling — moving a good trait is cheaper than rolling for a new one
-
Track your rolls — knowing the rates helps you budget gems effectively
-
Burn common traits — they provide negligible buffs and waste inventory space
The astd trait reroll guide community has documented that the average player needs between 50 and 100 rolls to see a mythical trait, depending on current rates. That means you should treat every roll as a significant resource investment and never reroll a unit you are not committed to maxing out. Patience and targeted rolling will always outperform blind gambling, even when the rates feel frustrating.
Capping Rerolls on Already-Good Buffs
Knowing when to stop is just as important as knowing when to start. If you roll an epic damage trait on your main carry, that is often good enough to clear all current content, and continuing to chase a mythical roll risks wasting gems that could go toward other progression systems. The opportunity cost of rerolling becomes steep once you have a functional trait, because those gems could instead fund summoning new units or upgrading existing ones.
The exception is when you have a surplus of gems and no immediate need for new units. In that case, chasing a mythical trait on your absolute best unit is a reasonable investment, especially if you have transfer items available to move the trait if you later pull a better unit. Just remember that the astd trait index shows diminishing returns—the gap between a good epic and a low mythical is smaller than most players expect.
Trait Buffs for Different Unit Roles
Different unit roles benefit from different astd trait buffs, and matching the right trait to the right role is what separates efficient players from those who waste resources. Damage dealers want offensive buffs, tanks want defensive ones, and hybrid units need a balance of both. Understanding these role-based priorities helps you evaluate every trait roll quickly and decide whether to keep, reroll, or transfer.
For pure damage dealers, the ideal trait is any astd damage trait with a high percentage, preferably paired with attack speed or range as a secondary effect. Attack speed multiplies your DPS more than raw damage in most scenarios because it affects every attack rather than just increasing the damage per hit. Range is slightly less valuable but still useful for keeping your units safe from enemy attacks.
| Unit Role | Priority Buff | Secondary Buff | Acceptable Tier |
|---|---|---|---|
| Pure DPS | Damage | Attack Speed | Epic or better |
| Hybrid Attacker | Damage | Health or Speed | Epic or better |
| Tank | Health | Defense | Rare or better |
| Support | Range or Speed | Damage | Rare or better |
| Staller | Health | Defense | Uncommon or better |
The table above reflects the general consensus from the astd trait index community, though individual unit kits can shift these priorities. A unit with an already high attack speed might benefit more from raw damage, while a tank with a healing ability might prefer health over defense. Always evaluate traits in the context of the specific unit you are equipping rather than applying a one-size-fits-all rule.
Building a Balanced Trait Setup
A well-rounded team needs a mix of damage and defensive traits spread across your roster, rather than stacking all your best traits on a single unit. While your main carry deserves the best mythical trait you can find, your tank and support units still need functional traits to perform their roles. A team with one god-tier damage dealer and three units with common traits will struggle more than a team with solid epic traits across the board.
This balance is especially important for Infinity Tower runs, where enemy scaling punishes any weak link in your lineup. According to player reports, teams with balanced trait distribution consistently outperform teams that concentrate all their best traits on one or two units. The astd transfer trait mechanic helps you achieve this balance by letting you redistribute good traits as your roster evolves.
Frequently Asked Questions
What is the best astd mythical trait for damage dealers?
Divine Strength is widely considered the best astd mythical trait for pure damage dealers because it grants up to 50% damage and 15% attack speed. The combination of raw damage and attack speed creates the highest sustained DPS in the game, making it ideal for carries that need to shred through high-health enemies quickly.
How often can I use the astd transfer trait mechanic?
The astd transfer trait mechanic requires a specific transfer item that is consumed each time you move a trait between units. These items are limited and typically come from event rewards or premium purchases, so you should use them sparingly. Most players save transfers for moving mythical traits from early-game units to their endgame carries.
Should I reroll a common trait on my main unit?
Yes, you should reroll common traits on your main damage dealers because the 5-10% buff they provide is negligible compared to what epic and mythical traits offer. Follow the astd trait reroll guide principle of targeting your carries first, and do not stop until you land at least an epic astd damage trait on your primary DPS units.
Do trait buffs stack with star level upgrades?
Trait buffs apply multiplicatively with star level upgrades, meaning the bonuses compound rather than simply add together. A unit with a mythical trait damage buff and high star level will deal significantly more damage than the sum of those individual bonuses suggests. This synergy is why investing in both trait quality and star levels is essential for late-game content.
Can I remove a trait without losing the unit?
Yes, use the astd transfer trait mechanic to strip a trait onto another unit, but it costs a transfer item and the target must be traitless. Alternatively, reroll directly—this replaces the old trait while keeping your unit. Both methods preserve the character entirely, so you never lose it.
