Hey ! (sry for my english, im not english speaking).
Colossus Slayer: Your tenacity can wear down the most potent foes. When you hit a creature with a weapon attack, the creature takes an extra 1d8 damage if it’s below its hit point maximum. You can deal this extra damage only once per turn.
But when I attack a full hit point unit, I still apply 1D8!
Moreover I have the impression that with the Hunter's Prey (or Marked Prey? i'm not sure about english spell) the effect does not always apply.
Others have the same case?
