Trollkin are young trolls. They have all the powers and weaknesses of trolls, and look exactly like smaller than normal adult trolls. Even an infant has the same ability to regenerate as an adult troll.

When you encounter trollkin, you can rest assured that there is a trollwife nearby (unless, of course, you’ve already slain her). They are as bloodthirsty as their parents; as such, determining the number appearing is done in a particularly unusual fashion:

Roll 1d6 for the number of individuals, and 2d6 for the number of hit dice. Divide the number of hit dice by the number of individuals to arrive at the hit dice of each individual. Note that a trollkin won’t be encountered having more than 6 hit dice, so if only one individual is indicated by the 1d6 roll but the 2d6 roll totals more than 6, you must increase the number of individuals. The referee should feel free to round the number of hit dice up or down as they see fit, or to allocate them in an approximately equal fashion if desired. Trollkin broods are rolled in this way owing to the fact that bigger or tougher individuals are likely to kill and eat the weaker ones, generally when their mother is out hunting.

Refer to the entry for trolls for details regarding regeneration, morale checks, and so on; except as noted above, trollkins share all these features with the adults
