Alexander's Domain Expansion

You rip a hole in the plane around you and fill it with an extraplanar space, forcefully imposing it on the area around you. The area within a 30ft radius of you becomes Difficult Terrain. You can choose any number of creatures to be immune to this when you cast the spell. Additionally, as a Bonus Action on your turn you may target a creature inside the area to make a Charisma saving throw dealing 5d6 force damage on a failed save, or half as much on a successful one as the plane's environment lashes out violently. A creature who fails this save is forcefully teleported to another space within the Domain. This space must be the ground or a floor.

At higher levels: When you cast the spell using a spell slot of 8th level or higher, the damage increases by 2d6 for each level above 7th.
