Deep Wilderness (level 49–50), north of the Lava Maze, single-way combat — Teleport interface → Wilderness → Giant Mole; four moles roam the plateau.

Mechanics

Pure melee — protect from melee.
Aggressive; the four moles share single-way combat, so one player fights one mole at a time.
Wilderness boss — beware of PKers, and no teleporting out above level 20.
Drops Big bones every kill, runes and supplies, a rare Granite maul and the Baby mole pet.
An easy boss with 200 hitpoints.
