Tremor Strike

When you strike a creature in melee, you cause the ground under them to tremble, disrupting them.  In addition to normal melee attack damage, the target takes your spellcasting modifier in force damage and cannot take reactions until the start of your next turn.

At Higher Levels:  At level 5, 11, and 17, you deal an additional 1d6 force damage if you hit with this spell.
