Mountain Trolls inhabit areas of the Southern Shiverpeaks and usually travel in groups.
- They are one of the few creature types that use attack skills from two weapon-mastery attributes (Hammer Mastery and Axe Mastery).
- They are often farmed, as they deal only physical damage, which can be entirely negated by Mist Form. One common spot to farm them is a cave just to the north-west of Droknar's Forge, where around 10 can be aggroed and killed using a build with AoE damage. Invincible Monks, 130hp dervishes, Death Blossom Assassins, Elementalists who increase their armor using Earth Magic, and numerous other builds can effectively farm them.
- Trolls have 91 armor vs fire damage.
