Time Splinter

The caster channels their magical potential from the rod of jet, invoking the powers of timelines that could have been. Upon a failed spell attack the previous turn, the caster is allowed to roll the potential damage of the spell they cast in the previous round and pull the damage forward from a fracture in time, adding 3d8 of Force damage onto that. The course of altering time this way will force the caster to take half the damage done to the target as Psychic damage to themselves. If the target saves against the caster's Spell DC, the caster still takes the Psychic damage.

At Higher Levels: When casting this spell at using a spell slot of 4th level or higher, the damage increases by 2d8 for each slot above 3rd level.
