You send a pulse of energy through the bond that links you and your companion, damaging any enemy that stands between you.
Any creature caught in a 5 feet wide line leading from you to your companion, must make a Dexterity saving throw. A creature takes 1d12 force damage on a failed save, or half as much damage on a successful one. On subsequent turns, you can use an action to send another pulse though the tether, and repeat the effect from when the spell was cast. If you or your companion move more than 30 feet apart, the spell ends.
At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d12 for each slot level above 1st.
