Scuttle ⟲ Trigger A creature that the giant crab can see targets the crab with an attack

Effect The giant crab scuttles to the side and gains a +2 circumstance bonus to AC against the triggering attack. After the attack resolves, the crab can Stride up to its speed in a straight line as part of the reaction.

Vulnerable to Prone If a creature critically succeeds on a check to Trip the giant crab, the crab is flipped over onto its back in addition to the usual effects. A giant crab that is flipped onto its back has a particularly hard time defending itself; instead of taking the normal -2 circumstance penalty to AC for being Off-Guard, it takes a -4 circumstance penalty to AC.

Speed: 25 feet, swim 15 feet
