Doomsayer's Prophecy

Channeling the disturbed magics of the weave, you look into the disaterous future of a particular creature, retelling your vision as an omenous prophecy to that creature. For the next 10 minutes, if that creature rolls a critical fail (natrual 1) on an attack roll, it has a mishap, attacking itself and dealing crit damage upon succeeding. The spell ends once the targeted creature rolls a natural 1.

For each additional spell slot, you may increase the number of targeted creatures by 1.
