The H.A.M. Hideout is the base of operations for the H.A.M. organization. It is located west of the Lumbridgegeneral store. To enter it, the player will need to pick the lock on the trapdoor to get in. This can be done with the player's hand, but a lockpick will increase the players chance of success.
At 20 Thieving, the same can be done with male H.A.M. members, for the same items, although better rates at higher items.
On the third time a player is caught thieving H.A.M. members that said player will be kicked out of the dungeon or be locked up in the cell with Jimmy the Chisel, which will require you to lockpick the door to exit.
If a player is wearing a full set of H.A.M. robes, (shirt, robe, hood, cloak, logo, boots and gloves.) in the first floor of the dungeon, the player is less likely to be kicked out when pickpocketing.
