Eldritch Strike

As part of casting this spell, make a melee weapon attack against one creature within range, otherwise the spell fails. On a hit, the target suffers the attack's normal effects, and a wave of force launches from your weapon at the target causing an additional 1d10 points of force damage.

This spell’s damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
