Magicka Serella

General of Undeath

8-level Necromancy (ritual)

This mighty magic creates an army of undead servants. It functions exactly as does the spell animate dead, except that with general of undeath you can create up to 30 skeletons or zombies as a number equal to twice your level.
 
At higher levels: When you cast this spell using a spell slot of 9th level, you animate or reassert control over 10 additional undead creatures for each slot level above 8th. Each of the creatures must come from a different corpse or pile of bones.
