Rock lobster

From Old School RuneScape Wiki
Jump to: navigation, search

Rock lobsters are found in the Waterbirth Island Dungeon's fifth sub-level, in Room 16. They are similar to giant rock crabs in the fact that they are initially disguised as large rocks, but they will attack the player as they approach. They have very high Defence (though they are weak to Magic attacks) and can hit up to 15 Hitpoints, but rarely hit over 11 Hitpoints. Their attack speed is as fast as darts on Rapid (they attack every second game tick), making them incredibly dangerous.
