Tarshak's sanctum

Tarshak's sanctum, also know as the Abomination Cave, is Tarshak's lair found in Brimhaven Dungeon. The location is visited during Hero's Welcome, where the Abomination is fought.

After the quest, players can find 15 bane ore rocks that can be mined, and a bane ore rockfall. The rockfall can be clicked on to fight the Abomination on phase 2 again, this time giving rewards upon death.
