When Shadow of the Colossus was first released in 2005 on the PlayStation 2 by Team ICO, it was greatly praised for its storyline, monsters, original soundtrack, and especially its stunning graphics. Imagine fans' delight, then, when it was remastered (for the second time) for the vastly superior PlayStation 4 and released in February 2018!

Though the picture on the 2005 edition was amazing for its time, there is an enormous difference between the original and the newer release, where we can enjoy the stunningly beautiful world and monsters in high definition, as well as enjoy some new challenges such as collectible items.


Pelagia is the nickname given to Colossus number 12, which was also called "Poseidon" during development. This watery menace is actually my personal favorite, unusual in its way and not as terrifying as some of the others. You do not need Agro for this mission.

Finding Pelagia

Just like Celosia, the previous Colossus, Pelagia is located north of the Shrine of Worship. Following the sword light, you'll see a different bridge to the one you've crossed several times earlier. It is identifiable by the two large pillars that flank it. Cross this bridge and there will be a cliff to your right.

Bearing right, you'll come to a shrine and a tree. Be sure to stop here for a stamina-improving white lizard tail and some energy-boosting fruit, respectively. Then follow the cliff, keeping the drop on your right-hand side. Before long, you'll come to another bridge with pillars either side of it. Cross it and enter the woods.

Turn right, where you'll soon find a way out of the woods (just be sure not to accidentally come out from the way you came). There is a cliff path along the water; follow it on Agro, though you are forced to leave her behind when you reach the waterfall.

There are some ruins you can climb; circle around the pillar until you reach another cliff path and follow it until it ends. Then jump into the water and approach the square, stone structures. One of them has already been destroyed. Swim towards it and the battle will begin!


Latching On

Pelagia will fire projectiles at you from his horns, but these can be easily avoided by holding R2, where Wander will dive under the water. Now you need to swim; make Wander go to the back of Pelagia, where you can climb up him from his tail. His entire back is covered in fur, but there are no magic sigils here.

Once you've reached his head, you have to be very careful not to get thrown off. Use your sword to hit the horns (Teeth?) on his head, which actually directs the Colossus towards where you want to go.

When you're close enough, leap onto one of the stone buildings. Hide behind the pillar, because Pelagia will fire more projectiles at you. The stone will protect you from them.

You may need to fire an arrow or two at this Colossus for it to make the next move. He will eventually raise his first two feet onto the platform, giving Wander the chance to jump onto his belly.

Finding Weak Spots (Magic Sigils)

Pelagia just has one magic sigil, which is on the fur part of his belly. However, it will take at least two rounds of climbing up onto his back, directing him to a building, and jumping onto his belly to deplete all of his health. Once he's lifted his front feet onto the building, his weak spot is open.

If You're Playing on Hard Mode

Pelagia still only has one weak spot in Hard Mode, but it requires more powerful attacks from Wander's sword to be defeated.

If you're still unsure of how to take Pelagia down, here is a useful video guide.

Some people dislike this battle because of its unusual requirements, but I think it's one of the coolest Colossi in the game! With this guide, you'll be showing Pelagia who's boss in no time, leaving you free to take on the 13th Colossus, Phalanx.
