Control Undead

You attempt to charm an undead creature you can see within range. It must make a Charisma saving throw, and does so with advantage if you or your companions are fighting it. If it fails the saving throw, it is charmed by you until the spell ends or until you or your companions do anything harmful to it. The charmed creature regards you as its creator/master.

When the spell ends, the creature knows it was charmed by you and will attack you as it is no longer under your direct control.

If the creature is being directly controlled by another being within 60 feat, make a contested Charisma check to see who gains/maintains control.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can target one additional creature for each slot level above 1st. The creatures must be within 30 feet of each other when you target them.
