Colossus Slayer

Your tenacity can wear down the most potent foes. When you hit a creature with a weapon attack, if the creature's current health is below it's health maximum, it takes an extra 1d8 damage. This damage can be dealt only once per turn, and takes temporary hit points into account.

I.E. If the Creature's has 100 maximum Health Points, but is at 95 current health, the 1d8 damage is applied. If the creature is at 95, but has 10 additional temporary hit points, so is at 105 effectively, the damage is not applied as it is above his maximum health points.

You are adept at instinctively getting out of situations that hurt.
