Physical Description: The Ichor of Undeath, also called ectoplasm, is a foul reagent thought to have first been used by the Furbolg tribes. The substance is produced by powerful and malicious undead, that the Furbolg of Azshara say are “so infused with evil that it coalesces into a sickly greenish goo”. The substance is a foul, ghostly green ooze, most commonly found in ancient ghosts wandering the lands they haunt, or within the ruined settlements themselves. Wraiths, spirits, abominations, banshees, ghouls, and other undead leaves lingering trails of ooze on areas they frequently inhabit. It should be noted that not all undead produce this ichor. The more restless, ancient, or foul-intentioned the creature, the greater of a chance they will produce ectoplasm.
Described Usage: The ichor of undeath has a few alchemical uses. It can be used to attune mediums and speakers for the dead to the presence and intentions of undead via various ritual. A vial of the ichor combined with two dried petals of the Black Lotus allows one to breath water when imbibed, but is rumored to make one see spirits in the waters of which they travel. The ectoplasm can be used to temper metal and cloth, or imbue is with properties of death or decay. Blacksmiths use this substance to temper a polearm, aptly named Blight, which inflicts disease on those it touches. Warlocks and tailors used this substance to infuse a special pouch to hold the stones or fragments of souls they collect. It is thought to aide in the retention of energies held within the pouch. Lastly, gnomes weaponize this substance in a rather terrifying device called a gnomish death ray. The device siphons life energy from the user to create an explosive blast towards an attacker. Each one comes with the disclaimer that death or serious injury may result in using it, thereby it is a seldom seen device. I personally deem this fortunate.
