Evolution rules
The Roblox game description confirms evolution and rank-up systems. The safe rule is to evolve keepers only: check Rank, role, Trait, Mutation, rarity, Boss egg value, and replacement risk before spending materials.
Fusion safety
Do not clean duplicate storage too quickly. Protect high Rank copies, Boss egg results, hidden monsters, rare rolls, Flora Hair, Snow Loom, and any monster with future Mega or route value before feeding material.
Normal vs Mega
Normal evolution can solve immediate route walls, while Mega Evolution needs rarer materials and better target checks. If Purple Crystal, Ferns, or Ice Crystals are involved, read Mega Evolution before spending.
