Darting Monkey

You have a heightened awareness in combat, and your darting strikes prevent your foes from distracting you or breaking your focus. When you hit a creature of your level or lower while that creature is flanking you, flanking doesn't make you Off-Guard to that creature. This benefit lasts until the start of your next turn or until the creature moves, whichever comes first. The creature can still help its other allies flank.
