Brought into being for the sole purpose of repelling the Allagan invasion, Sephirot inflicted ruinous losses upon the imperial army before finally being subdued and imprisoned in the central facility of Azys Lla.
Sephirot, the Fiend, was a deity once worshipped by a tree-like race native to Meracydia. One person needs to stand in each pillar to avoid raid damage (Tanks are a good choice for this.) After the arm sweep he will charge up a beam, spread out before restacking in the center.It will drop an air current on death, when it's marked by arrows stand inside to avoid the arm sweep.Once Storm of Words is dead, focus on killing the Binah/Cochma adds. Kill the Storm of Words add quickly, before it casts Revelation - if it casts Revelation you'll wipe.Various strategies can be applied, but easiest is just strafing to a side, having marked players go one way, and non-marked go the other way. He puts individual markers on two players which look like giant beams of light.
Pillar of Mercy - fist strikes on the blue circles with knockback - stand next to them (not inside otherwise you take the dmg) on the inside of the arena to avoid being knocked off the platform.This starts at around 60% health - be careful as you can fall off the platform during this phase.At the phase change (about 60% hp) he'll spawn Cochma and Binah adds, burn down Binah first, then Cochma.This attack has a 180-degree blast radius, has no cast and gives a Vulnerability Up debuff on hit, but can easily avoided by stacking behind him. Sephirot will turn to face a random player and hold very still with his arms up. These players should spread out to avoid stacking the damage taken. Ratzon - Approximately 6 players will get a small green AoE mark on them.All other players should stack on them to share the damage. Fiendish Rage - 1 player is marked with the 4 arrows indicator.And, in most cases, dungeons/raids under. I hear a lot during dungeon and raid chats that ignoring these warning signs are okay and can just be healed through. Generally, try and keep DPS and healers stacked up behind him for this phase. As a tank, its important to keep your eyes moving and not just concentrate on the placement of the mobs youre tanking its important to recognize the icons associated with these mobs. He has no casting bars or ground indicators, so this fight is extra fun!
