Attack of Opportunity

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.

Speed 25 feet

Melee Butterfly Sword +25 (agile, disarm, finesse, magical, parry, twin), Damage 2d4+15 slashing

Butterfly's Kiss

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

Mastermind's Eye

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.

Sneak Attack

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

Studied Strike

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.
