The troll might be a deadly creature or good for the experience, but the poison that can be distilled from his body fluids is one of the deadliest existing and very, very rare. The alchemical process to reverse the regenerative powers in the trolls blood is considered one of the most dangerous procedures for even the most skilled
Applying this greasy and purple liquid poison to a sharp or pointy weapon/utensil (needs to deliver at least one point of damage), it doubles the damage dealt with it every round. No save, just dissolving until the victim vanishes completely from the face of the earth. Healing won't work (but it helps to keep the victim alive a bit longer, even if in agony). Cure poison won't work, the damage is done. Resurrection is possible, but extremely difficult. There are rumours that fire and acid might stop the poison from working. Needless to say, it is very dangerous to try this. Surviving this will scar the victim for life (loose 2d6 CHA for all but friends and family), with no means, magical or otherwise, to get rid of them (short of a wish, maybe or imbibing a bottle of that stuff).
Imbibing a bottle of this poison is extremely dangerous, but legend has it that it might be rewarding, too. The trolls hit points are the base damage, double that every round for 4+1d6 rounds (save vs. death -5 every round for half damage). The pain is beyond describtion (no actions for the time and for 1d4 turns after that) and the body suffers (loose 1d6 CON, consider the character marked, maybe pale and thin...), but surviving this torture restores not only former wounds delivered by this poison (CHA back to former value), it also gives the character some troll abilities (according to damage taken):
1-49: Infravision up to 90 ftTrolls, however, will sense this and attack the character on sight. If he is famous, they'll even go as far as searching for him (characters level 9 or more: there is a 1 in 6 chance every day for 1d6 trolls to show up, if they can't get to the character for some reason, they'll wait and more trolls will show up...).
50-99: heal 1 point/round
101-199: heal 2 points/round
200+ : heal 3 points/round, limbs keep attacking when severed and can be reattached after the battle

P.S.: The "Social Status Table (NPCs)" I'm still banging my head against, is a bitch and will take some time (or rest). Good thing I didn't get paid for that.
