Gangrene

Sorcerors around the world have long yearned for a way to keep their corpses safe from ravenous mobs. After years of study, a talented Sorceror, renowned for their devotion to Bhyss (it is rumoured that Bhyss shared this knowledge in exchange for eternal damnation of the Sorceror) developed a formula, which, once imbibed, rendered their dead bodies so noxious that no foe, no matter how starved, could go within 10 feet of their decaying corpse without being repulsed.

The sorceror must not be too healthy, lest their natural immunities repel the disease, and not too weak, otherwise their body would crumble and die instantly at first taste of the liquid.
