Rose's WANDS OF HT were leaking this dark ichor... huh. Maid of Void might produce it and add it to drinks for some sinister purposes. Or "poison" arrows with it. Thief of Void might use it as beverage... okay, most classes would be able to use it as beverage. Page of Void injecting it by some means.. Like biting? Idk. Heir of Void might be able to turn into this ooze. While Prince of Void would be constantly wiping that darn ichor off furiously.

Okay congratulations, you’ve made me curious about how Horrorterror Ichor may taste like.
