Blood Spawn

Blood Spawn (BS) is a very powerful reagent that is in use on the Serpent Isle. It is created from Stoneheart and has several unique properties.

Serpent Isle
Bloodspawn is gained in a rather unusual way. After gathering Stoneheart, the rock is crushed to powder and the some of the caster's own blood is added -by using a bleeding device- to unlock its powers and transform it into the glowing powder known as Bloodspawn.

Bloodspawn can add serious power to a spell but has the drawback of being a very addictive drug to mages as well, which is why the mages of Moonshade had severely restricted access to the reagent. Mages would go over dead bodies to possess more of this reagent, such as Lorthondo, who had ventured into the Mountains of Freedom to gain more of the addictive substance. Vasculio's experiments with the reagent allowed him to turn into a vampire and he as well would search for more of it inside of Skullcrusher.

Trivia

 * Despite Bloodspawn being forbidden, most of the mages in Moonshade still have it, most prominently Filbercio when using Vibrate on him.
