Draining Touch

FEAT 2
Activity 1 action

You reach out your arm, grasping hungrily for a source of energy. Attempt a melee Strike. If you succeed, you deal 1d8 cold damage for every 2 levels you have to the target (1d8 per 2 levels cold), or double damage on a critical success.

Awakening You drain enough energy from a creature to leave it with lingering aftereffects. Your Draining Touch also leaves a creature Clumsy 1, or Clumsy 2 if your attack was a critical success.

Awakening You can pull away not just physical energy, but a creature's spirit as well. Your Draining Touch can deal your choice of cold, spirit, or void damage, changing the cold trait to spirit or void as appropriate.
