Scorched Cavern Troll
CREATURE 4Insatiable scavengers stalking the eternal gloom of the Darklands, cavern trolls consume all in their path-even rocks and minerals when more nourishing sustenance is scarce. These rocky goliaths can tunnel through stone with their iron-sharp claws.
Cavern trolls rarely venture to the surface world, for they have a debilitating vulnerability to sunlight that petrifies them on sustained contact. Unlike common trolls, cavern trolls can regenerate wounds dealt by fire. The crystalline nature of their skin, however, permits sonic attacks to neutralize their signature regeneration.
As cavern trolls age, their flinty skin becomes studded with small crystals and stones of various composition. Paragons of their kind have toothy maws replete with large, crystalline fangs. A typical cavern troll stands 14 feet in height and weighs about 2,000 pounds.
This monster regains the listed number of Hit Points each round at the beginning of its turn. Its Dying condition never increases beyond Dying 3 as long as its regeneration is active. However, if it takes damage of a type listed in the regeneration entry, its regeneration deactivates until the end of its next turn. Deactivate the regeneration before applying any damage of a listed type, since that damage might kill the monster by bringing it to Dying 4.
If exposed to direct sunlight, a cavern troll immediately becomes Slowed 1 and can't use reactions or Trample. The slowed value increases by 1 each time the cavern troll ends its turn in sunlight. If the cavern troll's actions are reduced to 0 in this way, they become Petrified until they spends at least 1 minute in darkness. Spells like Sunburst that create magical sunlight cannot petrify a cavern troll, but the troll is slowed 1 for 1d4 rounds after being exposed to such an effect.
A cavern troll can burrow through solid stone at a Speed of 10 feet. It can leave a tunnel if it desires.
The monster picks up a rock within reach or retrieves a stowed rock and throws it, making a ranged Strike.
