This tall creature has rough, green hide. Its hands end in claws, and its bestial face has a hideous, tusked underbite.
Longer description from Classic Monsters Revisited:
Lumbering out of the trees is, upon first impression, an enormous human with broad, thick shoulders and two solid, tree-trunk arms stretching down to almost drag on the ground. At further glance, its skin is a sickly, greenish hue and its eyes are pools of inky blackness. Its face is long and angular, with a solid, pointy chin and a crooked, hawkish nose, and its hair looks more like a mat of forest weeds and rests tangled and greasy on its heavy brow. There is an air of unsettled violence about it—its hands end in razor-sharp claws and its body seems taut and agile despite its size.

Morale Because of their regenerative abilities, trolls are fearless. Even flames or the presence of acid don’t slow them down—they always fight to the death.
