Rebel Brute

Trigger A creature within the monster's reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it's using. Effect The monster attempts a melee Strike against the triggering creature. If the attack is a critical hit and the trigger was a manipulate action, the monster disrupts that action. This Strike doesn't count toward the monster's multiple attack penalty, and its multiple attack penalty doesn't apply to this Strike.

The rebel brute makes a single Strike with a two-handed melee weapon. If the rebel brute hits a target that is their size or smaller, that creature is Off-Guard until the end of the brute's turn, and the brute can automatically Shove: Athletics it with the same benefits as the Shove action (including the critical success effect, if the Strike was a critical hit). If the brute moves to follow the target, that movement doesn't trigger reactions. This Strike has the following failure effect. Failure The target becomes off-guard until the end of the elite rebel brute's current turn.
