Prince of Tides is a dungeon & raids achievement earned for defeating an Unyielding Behemoth while you have the Tidal Surge effect during the Ozumat ecounter in Throne of the Tides on Heroic difficulty.
During phase 1 of the battle with Ozumat, an Unyielding Behemoth will spawn, which you must keep alive until the final phase of the fight. The behemoth will spray ink in a frontal cone, so the tank should attempt to keep it faced away from the rest of the party. Kiting the behemoth is advised because it stops often to do an strong AOE spell. When the final phase of the battle begins and Neptulon grants the party his buff, the party needs to quickly dispatch the behemoth and kill Ozumat to complete the achievement. Only killing the Unyielding Behemoth during the last phase will count for the achievement.
