Description
To spawn Venril Sathir, you need to give Venril Sathirs remains a Summoned: Firefly Globe which will spawn Spirit of Venril Sathir. You then give Spirit of Venril Sathir a Spell: Resurrection spawning Venril Sathir. Note that the Firefly Globe can only be summoned at night (8 p.m. - 8 a.m. game time), so you will likely need to cast the spell before forming your raid.
