==== Pre-Pull ====
There are two different strategies that players use in Duty Finder: 2-2-2-2 and 4-4, the former being more popular and generally used.
* : 2-2-2-2: Assign players to pair at cardinal positions. The pairs can be of any role, but keep in mind that it is better for melees to be paired with ranged. Most, if not all, will a pair a DPS with a tank/healer.
==== Phase 1 ====
Emerald Weapon will start with Emerald Shot, a heavy-hitting tankbuster on the main tank (MT). Then it will follow up with a raidwide magical AoE Optimized Ultima. Pre-shield + regen on the MT, and pre-mitigate the party.
Aetheroplasm Production: Blue and yellow orbs will spawn at the edges of the arena, slowly moving to the center. Players will have to pop two orbs with their pairs. Be warned that you cannot pop the same colored orb twice.
As soon as you see the boss cast this ability, get ready to run to the edge of your cardinal spot to pop your orb. Come back to the middle for shields and heals, and rotate accordingly based on the color of the orbs. (Note: Everybody will rotate the same direction no matter what.)
Divide Et Impera: A red stack marker will be assigned to a tank. Both tanks can stack, or one tank can invuln it. Do not stack if you are not a tank.
==== Phase 2 ====
== Achievements ==
== Musical themes ==
The Primals' arrangement of "Ultima" plays during the first phase. "The Black Wolf Stalks Again" plays during the second phase.
