Rock cake

A Rock cake is something of a ogre delicacy and is quite literally a cake made out of rock. Rock cakes can be obtained by stealing from the market stall in the ogre town of Gu'Tanoth, granting 6.5 Thieving experience, you will need a thieving level of 15 to steal the cake. A rock cake is required as a bribe in order to access the central parts of the Gu'Tanoth, which is necessary during the Watchtower quest. The player must give a rock cake to a guard in order to be allowed to climb over a rampart that blocks the way to a rope bridge. It deals 500 life points of damage if eaten, the damage isn't dealt until after you click to continue when your character says: "Ow! I nearly broke a tooth!".

According to Easta Buni, rock cakes are a "speshul Easta fud."

Rock cakes can not be gained until at least the player has gotten to the relevant part of the Watchtower quest.

Trivia

 * The rock cake is a play on the real world rock cake, which is a small cake with a rough surface containing raisins and berries.
 * You cannot kill your character by eating these. The lowest your HP will go is 25.
 * Before Evolution of Combat, rock cakes were used by players who wore full Dharok, since while fighting with full Dharok armour equipped with low hitpoints, the damage dealt by the wearer would be heavily increased. Players ate rock cake to inflict damage to themselves to use the full effect of the Dharok armour.
