Fire Trolls

Most trolls can regeneration from even grievous wounds but their regeneration can be halted by fire or acid. Very few soldiers or adventurers carry acid with them.   Fire trolls are not harmed by fire or at least, they are not harmed much by fire. This certainly won't negate their regeneration.   A fire trolls weakness is unsurprisingly water. Water will not hurt a fire troll per se, but a wet troll cannot regenerate physical wounds. This is common knowledge in East Colassia where fire trolls are fairly common but this is not well-known outside of East Colassia.   The normal remedy in East Colassia is to defeat a fire troll with weapons and the douse the remains with water. If there is not enough water available, cutting a dead troll into small pieces and burying the pieces sometimes stops a fire troll from regnerating again and even if they do heal, they won't heal fast. This remedy is not well-known even inside East Colassia.

Fire trolls are usually found in deserts or near volcanoes although magical anomalies or unusual migrations can allow rare fire trolls to pop up in unexpected places.

Like all trolls, fire trolls are not mortal, they are beasts. Compared to mortals they are dumb, but compared to other beasts they are not beasts. They have basic problem solving skills and have good predatory instincts. They will set up ambushes and withdraw if outmatched.   The thing that gives trolls a repuation for being dumb is that trolls are prone to greater risk taking behavior when they are hungry and trolls have powerful metabolisms and are very seldom sated.
