Otto's Grotto is an area west of Baxtorian Falls and where players can start Barbarian Training. To get here, rub a games necklace, or use the Barbarian Assault minigame teleport, and head south-west. Also near here is the entrance to the Ancient Cavern, a large whirpool at the end of a dock. Another way, through the Tree Gnome Stronghold, requires The Grand Tree quest. To bank any fish, players should head north to the Barbarian Outpost and deposit them in the bank chest near the Barbarian Assault minigame.
