Create Thrall

You touch an undead to enslave it. When this spell is used on an undead creature that is CR 1/4 or lower that creature must make a wisdom saving throw (DC 5 + character level) or be enslaved by the caster. If the creature succeeds the saving throw, it can not be effected by this spell for 24 hours even if it is casted again. In the event that the creature fails the saving throw, that undead is friendly to the caster and their allies. In addition, the undead can be commanded to do simple tasks and even attack enemies. The effects of this spell last until the creature dies or Create Thrall is dispelled. When the caster reaches level 7, Create Thrall increases in power. This spell now works on undead up to CR 4
