A Skragg is a smaller semi-aquatic relative of the common troll, but appears slightly stockier. It is sometimes called a swamp troll. It is more likely to communicate with potential victims rather than just attack, demanding some sort of tribute; it will normally leave would-be victims alone if its demands are met.

A skragg attacks with its claws and teeth. Like a regular troll, it has the ability to regenerate; however, a skragg must have at least 50% of its body immersed in water for its regeneration to take effect. Unlike a typical troll, a skragg regenerates from acid damage, but it fears fire like other trolls; the lower morale rating (in parenthesis) is used when the skragg faces attackers armed with fire.
