In Supergiant Games’ Hades, the gods of Olympus or Olympians will help Zagreus in his pursuit of escaping the Underworld. The Olympians help Zagreus because they believe that Zagreus wants to leave the Underworld to join them in Olympus, which is not true at all but what they don’t know won’t hurt them. Besides, Zagreus would probably not be able to escape the Underworld without their help.
One of the Olympians that helps Zagreus in his Underworld escape attempts is Poseidon. Poseidon, the god of the sea, is Zagreus’ uncle. In this guide, you’ll get to know Poseidon’s boons to help you in your Underworld escape attempts.
The Olympians help Zagreus by giving him boons which are upgrades that can make him stronger in battle. A boon can be obtained from completing chambers as a reward or by purchasing it from Charon’s Shop for 150 Obols. These boons, however, are only effective on the current escape attempt they were obtained and will disappear once Zagreus dies and goes back to the House of Hades.
Boons
Poseidon’s Boons cause Zagreus’ abilities to inflict Knockback, which can knock enemies around and can deal extra damage through traps and wall slam, while greatly increasing the damage he inflicts. Poseidon’s Status Curse is Ruptured, which affects the foe’s movement while rapidly dealing damage as they move.
Poseidon also has boons that offer Artifact currencies and raise the acquisition rate. Poseidon is one of two gods that offer these kinds of boons with the other being Dionysus.

Final Thoughts
Poseidon’s Boons are great to have as they offer the third highest raw percentage damage increase in the game. This damage increase plus the ability to knock enemies back to deal damage from wall slams and traps makes Poseidon’s Boons one of the must-have boons.
Additionally, it is worth mentioning that if you prefer to prioritize your Cast, Poseidon’s Flood Shot (Cast boon) is a frequent requirement for Duo boons.
It is also important to note that accepting all of Poseidon’s Boons at least once will complete one of the prophecies in the Fated List of Minor Prophecies called God of the Sea which will reward 150 Gemstones once completed.
