Kranf Niest, the mad doctor is an NPC found in Lawenilothehl. He appears to be always busy planning experiments, and serves very little purpose in the game. He will, however, reward the PC for completing the Kill Jharod quest on Hotzenplotz's behalf. This reward involves injecting the PC with the Healing skill at the cost of -1d3 to Learning, Willpower and Appearance permanently, and some corruption (scroll of dark predictions shows a total corruption increase of 1%). If the PC already has the Healing skill, the reward will instead be a stethoscope and scalpel.
