Valraun

Plane Shifting (1/Day). Valraun, as a Chosen of Asmodeus, can cast Plane Shift.

Command (3/Day). Valraun is able to cast Command  as if he used a 3rd level spell slot. When he casts Command he chooses up to 3 targets within 60 feet of himself but within 30 feet of each other. Each target must succeed on a DC 17 Wisdom saving throw or follow the command on its next turn. The spell has no effect if the target is undead, if it doesn't speak the language used, or if the command is directly harmful to it. His spell casting ability is Charisma.
