Memories of Fel, Frost and Fire

Memories of Fel, Frost and Fire is the Feat of Strength achievement earned for completing each memory during WoW's 15th Anniversary.

The quest, How Things "Really" Happened..., requires the completion of an epic trial of a 25-player raid that pits players against some of the most iconic bosses throughout World of Warcraft. There are three wings of the epic trial with three bosses each:


 * The Burning Crusade wing
 * Kael'thas Sunstrider
 * Lady Vashj
 * Archimonde
 * Wrath of the Lich King wing
 * Heigan the Unclean
 * Anub'arak
 * The Lich King
 * Cataclysm wing
 * Cho'gall
 * Nefarian
 * Ragnaros

Trivia

 * Instead of beginning the encounter from start to finish, players merely have to survive segments against the raid boss in question.
