Eldritch Strike

Crackling energy radiates from your fists. Make an unarmed melee attack against the target. On a hit, the target takes 1d10 force damage plus your Charisma modifier. 

At 5th level, you may make a second unarmed attack if both hands are free. At 11th level, you may replace one or both strikes with an attempt to grapple or shove the target. At 17th level, you may grapple or shove an opponent as a bonus action immediately after attacking. 

When attempting a grapple or shove with Eldritch Strike, make a Charisma(Athletics) check contested against a Athletics or Acrobatics check by the target. 

Damage caused by Eldritch Strike may be lethal or nonlethal as decided by the caster.
