Tales of the monstrous kraken that terrorize Azeroth's high seas were once relegated to myth... but no longer. By some ill means, the naga have bent Ozumat - the patriarch of all kraken - to their will and unleashed him against Neptulon and his followers.[1]
Phase 1: Kill the adds as they spawn. Move to avoid the Unyielding Behemoth's Shadow Blast.
Phase 2: Kill the Faceless Sappers. Avoid the inky voids that Ozumat casts. Tank should kite the Blight Beasts around in a circle until the phase ends. DPS should burn down the Sappers quickly, as they will kill Neptulon and reset the encounter otherwise; mark for kill order
Phase 3: Kill off any remaining Blight Beasts and burn Ozumat down before the DOT kills everyone. Healer should use AE heals since all of Ozumat's damage is AE. Pets can melee Ozumat but will be out of player LOS when they do, preventing use of abilities like Kill Command.
Heroic
Phase 1: Same.
Phase 2: Same. Be more careful about where the Blight Beasts go, since they have an aura that inflicts a stacking DOT on any who get near.
The encounter has 3 phases. During the entire encounter, Neptulon (who is friendly to players) stands in the middle of the room. If Neptulon is killed at any point during the encounter, the encounter resets. Ozumat does not appear until phase 2 of the encounter, and you do not fight him directly until phase 3.
The encounter begins when a player talks to Neptulon and selects the only conversation option.
Phase 1
Deep Murloc Invaders, Vicious Mindlashers and an Unyielding Behemoth will spawn. Kill any Mindlashers first, then the Behemoth. If you are attempting to complete Prince of Tides, then be sure to keep the Behemoth alive until phase three. The murlocs are very weak, easily AE'd even on Heroic. Avoid Behemoth smash.
Phase ends automatically after some time has passed.
Phase 2
Three Faceless Sappers spawn around the edge of the room; phase ends when they're all dead. They do nothing but channel an ability on Neptulon.
Blight Beasts periodically spawn; the tank kites them around, keeping them away from DPS/healer, as they have a damage aura on heroic.
Ozumat casts inky void zones on the floor that apply a stacking shadow damage debuff; everyone needs to stay out of them.
It is suggested that the tank concentrate on the Blight Beasts while all DPS concentrate on the Sappers; if the Sappers are killed too slowly, then Neptulon dies and the encounter resets. Mark for kill order.
Phase 3
Neptulon hugely buffs the players:
[Tidal Surge]ωϖ—Grants immense power to surrounding allies, increasing their health, damage and healing. Health increased by 500%. Healing increased by 500%. Damage increased by 2000%.
Once this buff is in effect, players should be able to easily kill all the Blight Beasts in mere seconds, even on Heroic.
Kill Ozumat (he's outside the room, attached to the outer wall) before his AoE kills you all. Use AE heals only in this phase, as Ozumat's only damage is his AE:
[Blight of Ozumat]ωϖ Unlimited yd range—Sprays the entire room full of blight, dealing 200 Shadow damage per second to all enemies. Stacks up to 200 times.
Once Ozumat is defeated, he flees, taking Neptulon with him. Neptulon's treasure hoard appears, completing the encounter.
