Description
Rock Trolls are cousins of the troll family that prefer to live underground. They can, however, sometimes be found outdoors.
A rock troll attacks with a bite or claw, resolving a single attack each round in White Box. It usually focuses on one target at a time.
Its regeneration repairs damage at 3 hit points per round at the beginning of the third round after it has been injured; this regeneration includes the re-bonding of severed members. The loathsome members of a rock troll have the ability to fight on even if severed from the body.
Having lived underground for so long, rock trolls have developed a calcified exoskin that looks and feels like rock. As such only blunt weapons, such as maces, clubs, and hammers will do full damage. If struck by an edged weapon, they will only take at the most 1-2 points of damage, Strength bonus notwithstanding. They will take further damage if magic edged weapons are used (the magical bonus).
In fact, if an adventurer with a Strength bonus uses an edged weapon on a rock troll and rolls a 1 on their to- hit roll, the weapon will have to make a saving throw or break. Any magical bonuses of the weapon will be added to the die roll of the saving throw.
When a rock troll is brought to below 1 hit point by a blunt weapon, it will shatter, sending pieces of rock in all directions. Characters must make a saving throw or be struck by flying shards, doing 1d6 points of damage.
When a rock troll disintegrates, and the detritus is investigated, it will be found that some of its rock-like composition may have been made up of valuable gems (Treasure type L).
It is also 10% likely that an exploding rock troll will drop a bladder full of liquid. This is a semi-permanent potion of regeneration, which will last for 1d12 months.
Rock trolls are not harmed by fire or fire-based spells, but take double damage from electrical attacks.
