How to Fuse Units in Multiverse Tower Defense

Fusion in Multiverse Tower Defense merges duplicate unit copies into a single stronger instance, raising base attack, SPA efficiency, or hidden stat multipliers depending on the unit type. The Fuse building processes transactions separately from evolution — fusion adds incremental power while evolution changes unit identity and abilities entirely.

Collect duplicates through summoning, crate openings, and Trading Plaza purchases. Keep at least one copy of every unit you might fuse before selling extras for Cash. Our summon guide explains when duplicate accumulation is intentional versus accidental.

Fusion costs scale with rarity. Mythic duplicates cost more Cash per fusion step but deliver the largest stat jumps. Budget players fuse Epics first because material requirements stay manageable while power gains remain noticeable on mid-game progression maps.

Do not fuse units you plan to trade — fused units may lose tradability depending on current game rules. Check the trading guide before fusing rare pulls that hold marketplace value. Shiny variants like the Shiny Kuzy from the RELEASE code carry premium trade prices unfused.

Optimal fusion order: stabilize your six-slot team, fuse carries to breakpoint levels where stats double effectiveness, then fuse support units for range coverage. Pair fusion sessions with enchant rerolls so each stat increase gets multiplied by Power or Eternal modifiers.

Codes providing crates accelerate fusion by flooding duplicates during banner events. Redeem kode aktif before fusion sessions to maximize duplicate intake. Raid mode also drops unit shards usable as fusion substitutes for specific universes.
