Butterfly Blade Warrior

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 warrior can make nonlethal Strikes with a butterfly sword without taking a penalty.

When the warrior successfully identifies a creature using Recall Knowledge, that creature is Off-Guard against their attacks until the start of its next turn; if they critically succeed, it's off-guard against their attacks for 1 minute.

The warrior's Strikes deal an additional 1d6 precision damage to Off-Guard creatures.

The warrior makes a telegraphed attack to learn about their foe. They make a melee Strike. On a hit, they can immediately attempt a check to Recall Knowledge about the target. On a critical hit, they gain a +2 circumstance bonus to the check to Recall Knowledge. The target is then temporarily immune to Studied Strike for 1 day.
