Trine

Pick three points within range. The spell creates vertical planes of force in connecting lines between each point, as well as an ethereal marker at the caster's location. Creatures must succeed on a Charisma saving throw or take 4d10 force damage and be teleported to the marker or the nearest unoccupied space on the same side of the zone isolated by the spell. If no such space is available, the target does not reappear until such a space becomes available, in which case they appear in that space, or until the spell ends, in which case they reappear in their original location. On a successful save, the target takes half as much damage and is not teleported.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot above 4th.
