Anime Legacy Simulator mutations are passive combat traits that modify a fighter's visual appearance and grant powerful battle effects. Developed by StarX Inc. on Roblox, the game features 10 distinct mutation types that can roll on any fighter rarity, providing stat multipliers, status ailments, or area-of-effect damage.
Because mutations can roll on standard, Shiny, and Secret fighters, pairing the right mutation with top-tier characters significantly boosts your overall DPS.
All 10 Anime Legacy Simulator Mutations and Effects
Each mutation in Anime Legacy Simulator alters a fighter's performance through active procs, permanent stat trade-offs, or damage over time. The table below outlines all 10 known mutations, their in-game descriptions, and tested mechanics based on community testing.
| Mutation | Primary Effect | Drawbacks / Activation Conditions | Tested Stat Multiplier |
|---|---|---|---|
| Earth | Substantially increases attack and ultimate damage | Reduces fighter attack speed | 2x (Double) damage per hit |
| Wind | Increases fighter movement speed and attack speed | None | Faster ultimate charge rate |
| Poison | Chance on hit to inflict poison damage over time | Requires hit proc | ~5 ticks at 20% of triggering hit |
| Fire | Chance on hit to burn target with damage over time | Requires hit proc | ~5 ticks at 15% of triggering hit |
| Ice | Slows enemies; detonates an explosive hit on count | Requires 7 consecutive hits | 2.5x damage on the 7th hit |
| Physical | Adds a chance to land a critical strike | Low proc chance (estimated 5% to 10%) | 5x base damage on critical hits |
| Water | Chance to trigger a double-strike effect | Requires hit proc | 2x damage via simultaneous strike |
| Lightning | Chance to cast an electric chain to nearby targets | Requires nearby enemies in range | Area-of-effect chain damage |
| Light | Periodic yellow aura boosting attack and movement speed | Temporary activation chance (~10% to 20%) | Temporary speed and attack buff |
| Dark | Greatly increases attack speed | Temporarily swaps damage with speed | Lowers hit damage while active |
Detailed Breakdown of Each Mutation
Understanding the exact behavior of each mutation helps you decide which fighter to build for raids, dungeons, or leaderboards.
1. Earth
Earth gives fighters a rocky brown aura and fundamentally doubles all outgoing damage, including ultimate attacks. In player testing, a unit dealing 544 base damage jumped to 1,089 damage with the Earth mutation equipped. The penalty is a noticeable reduction in attack speed, making it an ideal choice for high burst damage rather than rapid hits.
2. Wind
Wind acts as a balanced utility mutation by increasing both movement speed and attack speed. Because fighters move faster between targets and land attacks quicker, their ultimate meter fills significantly faster. It has no negative stat debuffs.
3. Poison
Poison provides a chance on any attack or ultimate hit to apply damage over time. When activated, the target takes roughly five damage ticks over time, each dealing approximately 20% of the damage of the hit that triggered the effect. If triggered by a high-damage ultimate, the resulting poison ticks scale accordingly.
4. Fire
Similar to Poison, Fire applies a burn damage-over-time status to enemies. Player testing indicates Fire deals roughly 15% per tick over five ticks, making it slightly lower in raw damage scaling than Poison, but still a solid offensive boost.
5. Ice
Ice slows target movement speed and features a guaranteed counter mechanic. After landing seven consecutive hits on an enemy, the ice detonates for an explosive blow that deals 2.5x normal damage. Unlike pure percentage-chance mutations, Ice offers guaranteed burst windows without relying on RNG.
6. Physical
Represented by a boxing glove visual, Physical gives your fighter a critical hit chance. While player testing observed a relatively low proc rate estimated around 5% to 10%, a successful critical strike deals a massive 5x base damage multiplier on basic hits and ultimates.
7. Water
Water grants a proc chance to unleash two hits in a single strike animation. When the splash effect triggers, your fighter effectively deals double damage (equivalent to a 100% critical strike) on that action.
8. Lightning
Lightning introduces chain electric damage. When triggered, lightning arcs from your target to nearby enemies within range. Its effectiveness scales in wave-based content where multiple enemies cluster together.
9. Light
Light randomly triggers a yellow glowing aura around the fighter. While the buff is active (estimated by testers to activate on roughly 10% to 20% of engagements), both attack speed and movement speed receive a temporary boost.
10. Dark
Dark temporarily swaps your unit's damage and speed values. In current testing builds, this substantially lowers single-hit damage in exchange for very rapid attacks. Most players consider this unfavorable unless your character build heavily benefits from hit counts rather than raw DPS.
How to Get Mutations via the Weather System
Mutations cannot be rolled at any random time; they are tied directly to the in-game Weather system.
- Monitor the Weather Widget: Look at the weather status bar located on the right side of the screen. This display lists the active weather pattern, the time remaining on the timer, and whether a mutation is available.
- Identify Mutation Windows: Neutral weather such as Cloudy or Clear grants general bonuses (such as increased fighter luck), but provides a 0% mutation chance. Special weather events introduce mutation drop rates. For example, Toxic Fog weather grants a 5% chance for any rolled unit to drop with the Poison mutation, while Meteor Showers offer separate rolling chances.
- Roll During the Active Timer: When a desirable weather event begins (usually lasting between 5 to 10 minutes), roll fighters from the Stars or Gacha banners.
- Any Rarity Qualifies: Any unit summoned during the weather event has a chance to inherit the active mutation, whether the unit is Common, Mythical, Shiny, or Secret.
While some community members have discussed potential methods to add mutations onto existing or exclusive fighters after summoning, existing gameplay tests have only confirmed acquiring mutations directly through Star summons during matching weather windows.
Frequently Asked Questions
Can Secret and Shiny fighters get mutations in Anime Legacy Simulator?
Yes. Testers have successfully pulled Shiny Mythicals and Secret fighters that feature mutations. The mutation check applies upon rolling the character from the Star while a mutation-bearing weather event is active.
Can you get a mutation during Clear or Cloudy weather?
No. Clear and Cloudy weather grant general buffs (such as +10% summon luck), but their mutation drop chance is set to none. You must wait for an environmental event like Toxic Fog or Meteor Shower.
Which mutation provides the highest single-hit damage?
Physical provides the highest single-hit multiplier at 5x base damage when a critical strike triggers. For consistent, permanent damage increases without relying on proc chance, Earth doubles base and ultimate damage on every hit at the cost of attack speed.
