Carry the black torch! Rouse the idle dead!
Henzell says...
  1. An aura which doubles stealth, causes accuracy penalties and cancels out haloes. Yredelemnul worshippers are immune to the accuracy reduction. Produced by profane servitors, Yredelemnul worshippers, and anyone who wears the {ring of shadows}.
  2. Used to be on Dithmenos and not Yred before their respective reworks in 0.32; Yred worshippers still got ambient umbra immunity at 3*s due to potential profane servitor allies.
