Unit Rarity Tiers
All Roll Anime to Fight unit rarity tiers explained — common to legendary, pull rates, merge ceilings, and when to fodder units.
Rarity hierarchy
Roll Anime to Fight uses standard gacha rarity stairs. Commons drop frequently from rolls — fodder for merges or instant fusion fuel. Uncommons slightly stronger but still early fodder. Rares form mid-game backbones when merged and traited. Epics compete through Wave 50 with investment. Legendaries top natural roll rarity and define late meta alongside code diamonds.
Luck upgrades shift pull distribution rightward — more epics and legendaries per 100 rolls at high luck. Low luck accounts see mostly commons and uncommons, making BLEACHPART2! Diamond Broly essential for bypassing bad RNG early.
Merge ceilings by rarity
Higher rarity supports more merge tiers and larger per-merge stat jumps. Merging two commons creates modest gains; merging two legendaries creates massive power spikes. Plan fodder pipelines: funnel commons into common bases until replaced, then cascade those merged uncommons into rare bases, eventually feeding your legendary or code diamond carry.
Never trait-reroll commons — shard cost exceeds lifetime value. Rares get budget rerolls only if they survive 20+ waves. Epics and legendaries receive full shard budgets on confirmed carries.
When to replace units
Replace when higher rarity pull shows same role with 30%+ better stats at same merge tier, or when tier list shifts buff your replacement. Transition smoothly — keep old carry merged until new carry matches merge level to avoid temporary power loss causing wave regression.
Code diamonds bypass rarity RNG at fixed power levels — Broly competes with mid legendaries, Ace with top legendaries. Treat codes as rarity shortcuts, not separate class.
