Destroy (or remove from play) all champions you own within aoe3. For each 5 skeletons destroyed a level 3 Bone Elemental is spawned within the area. For each 4 spirits destroyed a level 3 Collection of Souls is spawned within the area. For each 3 zombies destroyed a level 3 Corpse Golem is spawned within the area. For each 3 stitched destroyed a level 3 Stitched Merged is spawned within the area. For each 3 any remaining champs a random blackguard/dreameater/magician is spawned. Clones and summons count as 1/2 for this spell. Spell purpose: counter swarm, reduce micromanagement, sacrifice almost dead champs. Flavor: all resulting champs are already existing yet barely run "merged" of corresponding race. Cost: 35 if champs are removed from play or 55 if they are destroyed.
I like the spell idea, but not everything in one. stitcheds NEVER use their meld ability so a spell form might be funny. like 3 non stichling stitcheds together would make one big stitched with all upgrades.
