Cimmerians fear not creatures of flesh and blood but those of an undead nature cannot be killed by normal means. Forced to adapt people of the Forgotten Tribe found a way to make the rotting flesh sear by coating their weapons with this salve.
This item can be obtained by killing Cimmerians in the Mounds of the Dead as a random drop. It can be equipped to a weapon to do damage to the undead in the same fashion as poison to the living. The poison lasts for 10 strikes, before it has to be reapplied. Multiple applications do not stack.
