Lobster pot

A Lobster pot can be used at level 40 Fishing to catch Lobsters in Cage/Harpoon fishing spots by selecting the "Cage fishing spot" option. They can be bought from:
 * Harry in Catherby (for 20 coins)
 * Gerrant in Port Sarim (for 20 coins)
 * Other players

They can also be obtained as a drop from Dagganoths or from a spawn in the Fishing Guild.

Lobster pots are used in the Dragon Slayer quest as an item the oracle tells players to use for opening the door leading to the chest of Thalzar, which contains 1 of 3 map pieces needed to continue.

Common Lobster fishing spots include Catherby, Karamja and the Fishing Guild.
