Raise Zombie

You can put a soul you control into a corpse and succeed on a Constitution Save equal to your Transformation DC to make an undead creature under your control, the DC raises if the soul is a stronger one. Whenever an undead creature you control is reduced to 0 hit points, it may immediately move up to its full speed and make an attack action before dying. This feature has no effect if the creature has been reduced to 0 hit points by radiant damage.
