Washed Ashore is a treasure map in God of War Ragnarök you can collect and complete in Alberich Island.

Alberich Island - Treasure Map 1 - Washed Ashore

The Treasure Map for Washed Ashore is found on Alberich Island, however, you cannot reach it until you've completed the Forging Destiny main quest and picked up a new piece of equipment. Prerequisite: Complete the Forging Destiny main quest

• Rewards:
  • Amulet Enchantment - Jotunheim's Virtue
  • 1 Asgardian Ingot
  • 1 Luminous Alloy
  • 1 Petrified Bone
  • 40 Shattered Runes

Once you've completed Forging Destiny, return to Alberich Island's main beach, then look for the Wind Vent on the right-hand wall: use your new equipment on the Vent, then climb up the wall. From here, head right up the wooden ramp to reach an elevator, but the lift is down at the bottom. To raise it, fire a Sonic Arrow at the Soundstone rock on your left, then head through and right down the newly cleared path. At the bottom, look right towards the elevator, and you can see a rock with a Wind Fissure on it: throw a Draupnir Spear at it and then detonate it, allowing the geyser to flow and raise the lift. Head on over to it and use the grapple point to make it onto a wooden platform. There's a Red Coffin hidden under the elevator, To get it, turn around, then plug up the geyser using the Leviathan Axe. This will lower the lift, allowing you to grapple back over and then find the Red Coffin hidden behind the wooden wall. Once you've made it across, look for the grapple point on the left and use it to get onto the island. There, the Treasure Map will be visible on your left, under the yellow gear.

Washed Ashore Buried Treasure Location

Once you've collected the Treasure Map, head for the South end of Dragon Beach and dock the boat on the shore. The Buried Treasure will be glowing on your right, close to the giant skeleton in the water.
