Stick Together (Feat)
You stick close to your allies in combat.
Prerequisites: Level 16
Benefit: When an adjacent ally with this feat moves using a move action, you can move up to your speed as an immediate action. Your ally only has to be adjacent to you at some point during their movement for you to use this ability. However, if you end your movement anywhere that is not adjacent to your ally, you are Rattled on your next turn. This movement provokes attacks of opportunity as normal.
Note: This is a Teamwork Feat, meaning it does nothing unless you and at least one other member of your party each possess this feat.
