This spell creates 100 undead servants. To cast this spell, there must be 100 corpses of Medium or Small humanoids within range and it must be nighttime. these corpses don't need to have all their parts.   Your spell imbues them with necrotic power, raising them as undead creatures. Your "freshly" made 100 undead servants are grouped into 10 squadrons, each having 9 Skeletons/Zombies(your choice), and 1 Wight(who will act as an officer).   Your army is under your control for 1 week, after which the wights stop obeying any command you give them and the Skeletons/Zombies collapse in a lifeless heap. To maintain control over the army for another week, you must cast this spell twice in one day on the army again before the current 1-week period ends. This use of the spell reasserts your control over the remaining creatures you have animated with this spell, rather than animating any new ones.   Ascended Necromancy. This Spell costs 2 spell slots to cast. A 6th level spell slot, and a 5th level spell slot.
These spells don't count against your total number of spells known.
