Mass Resurrection

Mass Resurrection is a Guild Perk granted at guild level 25 that resurrects all raid and party members.

Trivia

 * Mass resurrection is one of the spells used by the paladin hero unit in WarCraft III (although it's just called "Resurrection" and resurrected maximum 6 units). It seems Blizzard at one point was planning on introducing it as a paladin spell in World of Warcraft, making it one of the new spells in TBC. It didn't make it past beta and was replaced with Avenging Wrath instead.
