Stomp

A model with this rule can make a Stomp in addition to its other close combat attacks (including Breath Weapons). A Stomp has Always Strikes Last, and inflicts D6 (or D3 against lone Infantry models and skirmishers) automatic hits, at the model's Strength, on one enemy Infantry, War Beasts or Swarm unit in base contact with the model and are
randomised as Automatic Hits.

Unless specified, any rules that apply to the model’s normal attacks do not apply to its Stomps.
