From Lost Fables Wiki
Trolls appear to be a mix of a Rehk-Ogri and a Mongrel Voudr, having disgusting greenish mottled skin, but all the rest of the characteristics of the massively strong ogres. They tend to be somewhat more intelligent than their ogre cousins, though they usually still disdain weaponry, and they’re certainly faster. They eat nothing but the flesh and blood of sentient creatures, and the more gorged they are on the stuff the more quickly they regenerate. All in all, trolls are extremely fearsome foes.
Caves, under bridges, in dense forests
Extremely hostile and territorial. Loves eating, even when not hungry.
Extreme. As if their strength wasn’t bad enough, Trolls are smart enough to lay basic traps and use ambush tactics, and they regenerate any wound that they take not caused by fire.
Very strong, somewhat clever, regenerative flesh.
Fire is extremely effective against them, and when fighting in direct sunlight their regeneration abilities are greatly weakened.
