Poseidus is a rare elite seahorse which drops the Reins of Poseidus mount. Up until Legion, he was one of the most difficult mounts to own, due to his extremely long respawn rate, said to range from 72-120 hours. However, the item is BoE and has been listed in the AH at ridiculous prices since Cataclysm.

In Patch 7.3.2, the respawn rate was hotfixed to 4-7hrs. Also, if you’re grouped with four other people, you should all get the mount as a personal loot item.

There are five spawn points, one in Abyssal Depths and four in Shimmering Expanse.

Not only was I taken on my own whirlwind trip last night, but I was also gobsmacked to see Poesidus in-game because I’d never seen any physical proof he existed before today. When I managed to target him, he was at full health and coming straight towards me. OMG! I couldn’t believe my luck so I quickly engaged him (trying to take a few screenshots) before finally killing him. For those wondering, I found him at this final location. Not surprisingly, he’s an easy kill at 85.

Poseidus has three abilities:

  • Bubble Charge – Charge the target in a shower of bubbles, dealing Frost damage.
  • Bubblebeam – Shoot bubbles in a cone in front of the caster, dealing Frost damage.
  • Seascape – Attempt to escape from combat and regenerate health.  Damage taken will remove the healing effect.

Since I’d killed him so fast, I didn’t notice any attempt to escape but you can just see his Bubblebeam in that first pic.

In addition to 89G, this is what he dropped

That’s two rare mounts in 12 hours!!

Unlike the Vashj’ir Seahorse from questing, Poseidus can be mounted in any body of water. The only exception is Nazjatar, where you can ride any of your underwater mounts with the aid of a Budding Deepcoral.

Hmm, I wonder if Aeonaxx or Time Lost are up?
