Strange Strikes

5th-Level Artificer Feature

The degree of control you exert through your Strings grows. Starting at 5th level, when the creature attached to your Marionette Strings makes an attack, you can use your reaction to cause them to make one additional attack.
In addition, when a creature attached to your Strings hits a creature with a melee attack, you can expend a spell slot to empower their strike. Their strike deals an additional 2d6 force damage for a 1st-level spell slot, and an additional 1d6 force damage for each spell slot level above 1st.
