Multiple rock crabs

A player aggravating multiple rock crabs.

​​Rock crabs are aggressive monsters that look like harmless rocks while they are disguised, but when unsuspecting passers walk by, they attack; however, once their target leaves the nearby area, they are no longer aggressive. It should be noted that, unlike most other enemies and NPCs, rock crabs are not marked with yellow dots on the minimap; this is probably due to the fact that the crabs' appearance camouflages them as rocks. Players can tell if a rock is a crab or not by looking at the rock's shape, Rock crabs are tall oval shaped, but normal rocks in their area are mostly in large clusters of shattered pieces. It should also be noted that, as with most aggressive monsters, rock crabs will stop attacking a player if they have not left the surrounding area in a considerable amount of time (roughly between ten and twenty-five minutes). To fix this, simply run out of the surrounding area (to be sure, run halfway to the entrance to the village of Rellekka or simply enter and exit the entrance to Keldagrim) and run back, at which point the rock crabs will once more be aggressive. As they are "dormant" until "awoken" by a passing player, rock crabs cannot be attacked until they are made aggressive once more. They hit fairly low but if you are a low level you should bring food. These are very good for training, for a wide range of combat levels. A low defence, and high hit points of 50 hp (200 xp), makes them a popular spot for training (usually Ranged).Rock Crabs give 50 slayer exp each.
