You can do a “fighting retreat” if engaged at melee range
- You must move 180 degrees away from your current facing, and only move up to half your movement rate,
- and you have to move in a straight, non-diagonal line; there can’t be anything blocking your path, including friendlies.
- A fighting retreat does not trigger opportunity attacks,
- A fighting retreat still allows you get an attack in the melee phase.
Alternately, you can do a “full retreat” if you’re engaged at melee range
- You can move up to your full movement rate away from your opponents engaged at melee range,
- you can’t move forward or through your enemies, but you could move sideways or to the rear.
- A full retreat does trigger opportunity attacks, but not at a bonus and you get to keep your shield bonus to AAC.
- In a full retreat you lose your attack in the melee phase.
