Venril Sathir remains

[Thadeus]

Spawn time is supposed to be 12 & 24 hours after time of death. Was variance added to this NPC?

Information is pretty sparse but from everything I've read and heard from classic players, it is spawned at least once 24 hours after the kill, and meant to drop 2 stones for epics. Did not spawn after 24 hours.
