Outflank

You look for every edge when flanking an enemy, having trained to work exceptionally well with your teammates to overwhelm and exploit gaps in a foe's defenses.

Whenever you and an ally who also has this feat are within 5 feet of the same creature and wielding melee weapons, you gain a +1 bonus to hit for each ally with this feat who qualifies. Whenever a creature with this feat lands a critical hit against a hostile creature, one other creature with this feat may use their reaction to make a melee attack.
