About this game

Merge in the middle of the fight.

In Aetherfuse, your elemental spirits fight on their own. Your job is to fuse them at the perfect moment. When two spirits stand side by side in battle, a merge button appears between them. Tap it, and something stronger is born right there on the battlefield.

■ Merge mid-battle
• Same spirits → level up (up to Tier 4)
• Different spirits → a brand-new spirit from a recipe
• Two recipe spirits → a legendary Ultimate

■ 9 elements, 56 fusions to discover
Wind, Stone, Lightning, Fire, Water, Wood, Light, Dark and Poison. Find Sandstorm, Plasma, Sun… and 20 Ultimates like Typhoon, Phoenix and Aurora. Every new discovery is recorded in your Element Codex and makes its elements permanently stronger.

■ Hold back the Corruption
Corrupted elementals pour in wave after wave. Clear story chapters, take down raid bosses, and sweep the field with your tower's Purifying Pulse. Terrain like lava, ice and storms changes every fight.

■ Build your deck
Pick five elements for each run, hit the enemy's weak element, upgrade your spirits with crystals, and level up your tower mid-battle for new weapons.

■ Endless Challenge
How long can you hold out? Climb the weekly ranking.
