Void Spike

A bolt of scintillating dark energy strikes one target for 3d10 force damage.  If the damaged creature is Large or smaller in size, in must succeed a DC15 STR saving throw or switch places with the caster.  Creatures that are huge or larger are not teleported but instead take and additional 2d10 force damage if they fail this saving throw.  If a large or smaller creature is killed by the damage from a void spike, they switch places with the caster automatically.

At Higher Levels.  When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 and the range increases by 10 feet for each slot above 2nd level.
