Stomp is a threshold ability. Similar to its basic counterpart, it knocks the target back and stuns them whilst dealing 40-200% ability damage.
Against monsters that are not stun-immune, Stomp works well in conjunction with Slice or Punish. This is because Slice's damage range is buffed to 80%-146% and Punish deals an extra 94% damage when the target is stunned.
This ability shares its countdown timer with other threshold stuns (Forceful Backhand, Tight Bindings, Rout, Deep Impact and Horror).
