Undead Torch

You cause up to two corporeal undead to burst into sickly blue flames. The undead must be either willing or controlled by you. The flames do not harm the undead, but instead allow them to inflict an additional 2d6 fire damage with each of their physical attacks. These flames shed dim light in a 10-foot radius.

At Higher Levels: When cast at higher levels, you may select an additional two undead to make Undead Torches of per level above 3rd.
