After the release of patch 4.1 in Stormblood, a brand-new 24 player raid was added to Final Fantasy XIV: The Royal City of Rabanastre. Without further ado, let's get started with our complete guide to Return to Ivalice: The Royal City of Rabanastre.
The first part in the Return to Ivalice series of 24-player raids, The Royal City of Rabanastre is meant as next major endgame raid to defeat once you've already completed the eight-player Omega and new four-player dungeons in Stormblood.
Return to Ivalice: Rabanastre - Rofocale
Phase One: Mark like Mateus, where it's west, north, and east. Rofocale will begin the fight with Crush Helm. This is a debuff for the main tank. Healers should remove it when the debuff stacks to four.
Phase Two: Avoid all AOE's, especially blue ones. He will do Chariot and Cry of War, followed by Trample, and then Chariot/Cry of War again.
Return to Ivalice: Rabanastre - Hashmal Boss Fight
For this fight, it is also important to remember your markers. Unlike Mateus, the usual marks work: west (A), south (B), and east (C). Hashmal begins with harsh AOE's like Quake IV and Jagged Edge.
