How Roll Anime to Fight Works: the Roll → Merge → Mutate → Defend Loop

Roll Anime to Fight runs on one tight gameplay loop, and understanding it up front saves you hours of wasted Gold. You roll for anime-inspired units using Gold, merge duplicate copies to level up your strongest version, chase mutations that multiply a unit's stats, then place your team to defend against escalating enemy waves. Everything you do — every currency, every upgrade — feeds back into pushing further into those waves.

The game is co-op for up to 6 players per server, so you can pool damage with friends, but your inventory, rolls and upgrades are all yours. Because rewards scale with how deep you clear, the goal is never "roll the flashiest unit" — it is building a small, well-leveled core of mutated carries and steadily upgrading your Luck so better pulls come more often. If you keep the loop in mind, every decision below becomes obvious.

Tip: Codes are one of the fastest ways to fund the early loop — they hand out Gold and Trait Shards. This guide does not list them (they rotate constantly); grab the current working list on our Roll Anime to Fight codes page and spend the Gold on Luck as described below.

Rolling for Units & Understanding the 5 Rarities

Rolling is where every run starts. Each roll costs Gold and returns a unit somewhere on a five-tier rarity ladder that runs from Common up to Godly. The higher your Luck stat, the better your odds of landing a rare unit and of that unit arriving with a mutation attached. There are no official public per-unit percentages for this game, so ignore any site that quotes exact drop odds or a "pity counter" — those numbers are invented. What is reliable is the direction: more Luck equals more rares and more mutations over time.

Practically, that means you should roll in bulk rather than one at a time once you can afford it, and you should not get attached to early Common and Uncommon pulls — they exist mostly to become merge fodder. Keep rolling to build duplicates of your better units, because leveling comes from merging, not from a single lucky pull. A well-merged rare will out-damage a lone higher-rarity unit that has never been leveled.

Merging Duplicates to Level Your Team (and Protecting Mutations)

Merging is the leveling system. When you roll two or more copies of the same unit, you combine the duplicates into one to raise that unit's level and stats. This is why bulk rolling matters — a pile of duplicates is not clutter, it is XP. Follow these steps:

  1. Identify your best copy of a unit — the one with the highest rarity or, more importantly, the one carrying a mutation.
  2. Merge plain duplicates INTO that best copy so the level and stats stack onto the version you want to keep.
  3. Never feed a mutated unit into a plain one — the direction of the merge decides which unit survives, and merging the wrong way destroys the mutation.
  4. Repeat on your 3–4 core carries instead of spreading merges thin across a dozen units; a few deeply leveled units beat a wide shallow roster.

The single most common beginner mistake is merging a mutated copy as fodder because it looks like "just another duplicate." A mutation applies a large stat multiplier, so a mutated unit is almost always worth more than a higher-rarity plain one. Preserve mutations on every merge and your damage climbs far faster.

Mutations Explained: Nen, Titan, Diamond, Gold — What to Keep

Mutations are bonus modifiers that roll onto a unit and multiply its stats. They sit on their own tier ladder, independent of the unit's base rarity, and that ladder tells you exactly what to keep and what you can risk as fodder:

MutationTierWhat to do
NenS-tierKeep always — top carry material, never fodder
TitanS-tierKeep always — top carry material, never fodder
DiamondA-tierKeep — strong early/mid-game carries
GoldB-tierKeep and use until you land A/S mutations
Standard (none)C-tierSafe to merge as fodder into mutated copies

A concrete example from the current meta: Diamond Broly is the best early-to-mid AoE carry in the game because that A-tier Diamond multiplier turns him into reliable crowd damage, while Diamond Ace peaks later during Waves 65–76 as a single-target DPS window. Both are Diamond-tier mutations on strong base units — proof that an A-tier mutation on the right unit carries entire runs. Only ever consider a Gold-tier or standard unit as fodder; hold every Nen, Titan and Diamond you pull.

Tip: Raising your Luck upgrade increases mutation roll odds as well as rarity odds, so the fastest route to more S-tier mutations is investing Gold into Luck rather than endlessly re-rolling at a low Luck level.

Spending Gold: Luck vs Slot vs Inventory Upgrade Priority

Your upgrade tracks — Luck, Gold, Slot and Inventory — all draw from the same Gold pool, so priority matters. Spread evenly and you stall. Here is the order that pays off fastest:

  1. Luck first, always. Luck boosts both rare-unit and mutation odds, which compounds every roll you make afterward. Early Gold spent here pays back more than anywhere else.
  2. Slot next. More deployment slots let you field more of your leveled carries at once, directly raising the damage you bring to each wave.
  3. Inventory when you're overflowing. Expand storage only when you are genuinely running out of room to hold duplicates you still need to merge.
  4. Gold-generation track as a steady background investment so your future rolls and upgrades stay funded.

Do not fabricate a budget from guides quoting exact upgrade costs — the game does not publish fixed prices and they scale as you level. The principle that holds regardless of the numbers: pour early Gold into Luck, because better rolls make every other system stronger.

Trait Shards & the Trait Machine (Rerolling Passives)

Beyond Gold, the currency that separates a good unit from a great one is Trait Shards. You spend them at the Trait Machine to reroll a unit's passive trait — the damage, attack-speed or Gold-gain bonus baked into it. A carry with a strong damage or speed passive on top of an S-tier mutation is what clears the deepest waves.

  1. Save Trait Shards for your locked-in carries — the Diamond and Nen/Titan units you already plan to keep, not throwaway rolls.
  2. Reroll at the Trait Machine aiming for damage or attack-speed passives on offensive carries, and a Gold-gain passive on a unit you farm with.
  3. Stop when you hit an S-tier trait that suits the unit's role rather than chasing a marginally better one and burning your whole Shard stock.

Trait Shards, Godly Essence and Infinite Tickets are all currencies that codes can grant, which is another reason to keep the codes page handy — a fresh code can fund a Trait Machine session that would otherwise take a long grind.

Pushing Waves & the Infinite Tower (Checkpoints 40 → 76+)

Wave-defense is the real test of your roster, and the game has clear checkpoints that tell you whether your team is on track. Use them as benchmarks:

CheckpointWhat it means
Wave 40A-tier viability threshold — well-merged rares with S-tier traits carry unlucky accounts to here
Wave 50The wall where plain rares stall and you really need mutated carries
Waves 65–76Diamond Ace's peak DPS window opens up
Wave 70+Diamond Ace overtakes Diamond Broly as your primary carry

If you are having a rough RNG streak, do not despair — a couple of well-merged rare units with S-tier traits can carry an unlucky account to around Waves 40–50. To break past that, lean on your Diamond carries: Diamond Broly handles the early and mid waves with AoE, and once you reach Waves 65–76 the Diamond Ace DPS window opens, with Ace overtaking Broly as your main damage dealer from Wave 70 onward. Keep merging plain dupes into these carries between attempts and each run pushes a little deeper.

When you want an endless challenge, spend Infinite Tickets to enter the Infinite Tower — an endless mode that keeps escalating for as long as your team survives. It is the best proving ground for a maxed carry and a good sink for the Godly Essence and traits you have been stacking. The latest content, the "Bleach Part 2" event (last updated July 28, 2026), added Diamond Broly, Diamond Ulquiorra and Gold Kenpachi units alongside the Infinite Tower, so the roll pool is fresh right now.

Frequently Asked Questions

How do mutations work in Roll Anime to Fight?

Mutations are bonus modifiers that roll onto a unit and apply large stat multipliers. They form a tier ladder: Nen and Titan are S-tier, Diamond is A-tier, Gold is B-tier, and a standard un-mutated unit is C-tier. Raising your Luck upgrade increases the odds of rolling both rarer units and mutations, but there are no official public per-unit percentages — treat any site quoting exact mutation odds as guessing.

Should I merge mutated units in Roll Anime to Fight?

Never use a mutated unit as merge fodder. Always merge standard duplicate copies INTO your best mutated version so the mutation is preserved and the unit levels up. If you merge the mutated copy into a plain one you lose the multiplier, which is the single most common early mistake. Keep every Nen, Titan, Diamond or Gold roll and feed plain dupes into it.

Does Roll Anime to Fight have codes?

Yes. Roll Anime to Fight has a working code system that grants Gold, Trait Shards and other currencies. Because codes rotate and expire, we track the current active list on a separate page rather than here — see our Roll Anime to Fight codes page for the up-to-date, dated codes and the exact redeem steps.
