God Of War Ragnarok is full of some of the greatest story moments that keep players on the edge throughout the playthrough. While it nails the storytelling, it also perfectly creates big and full realms for you to explore, complete side missions, do tasks, and fight monsters along the way. Each of the nine realms is full of life and things to keep players entertained as they explore and become immersed in the Norse realm.
Under The Rainbow is one of the game's many side-quests, which is located within Vanaheim. In order to obtain the Under The Rainbow treasure, players must first go and find the treasure map in order for the treasure to spawn and be obtainable. This treasure is relatively simple to obtain and will see Kratos paddling down the river just a short distance.
Obtaining The Treasure Map
Players must first make their way to the Noatun Gardens to obtain the map for this treasure. It's easiest to travel to the Mystic Gate of the River Delta. From here, get in a boat and follow the river east, then north, with the gardens soon appearing to your right. Then, get off your boat at the nearby beach and fight the few monsters in the center of the garden.
These monsters can be a bit more formidable depending on when you attempt this treasure, as this is one of the earlier treasures you'll have access to in a playthrough. After clearing the monsters of the garden, facing from the beach, head to the back left corner. To the right of the overgrown building and at the foot of some rocks will be the map, slightly hidden among some tall grass. Picking up the map will begin the quest and have the treasure spawn at its designated location.
Finding The Under The Rainbow Treasure
After obtaining the treasure map, return to your boat and head back upstream. Heading back the way you came, turn down the small stream to the left before reaching the River Delta gate. Following this smaller stream will eventually open up to a larger beach before a steep cliff. Disembark and head straight toward the bottom of the cliff.
At the bottom of the cliff will be a small section that will allow Kratos to climb. Make your way up the cliff until you reach the top. At the top, look to the right side along the edge and see the bright gold light marking the location of the treasure. Approach the treasure and interact with it to see Kratos digging the items up, thus completing the quest.
Completing this treasure will award Kratos with 50 XP and additional items. You will obtain 10 Shattered Runes, 1 Stonewood, 1 Dwarven Steel, and 1 Honed Metal.
