The Seven Deadly Sins: Origin dropped a new update on June 25 as their 100-day anniversary celebration, featuring new heroes, progressions, combat additions and seasonal events. Since the events are time-limited, it is best to grab all the collectibles and upgrades before it ends on July 15. In this guide, we will explore all the chests on the new location Spray Island as part of the ‘A Midsummer Day’s Dream’ event.
How to Access Spray Island

You will only be able to unlock Spray Island once you have completed the game up until Main Story Act 4. Once you have done that, check under the Quest tab for “A Midsummer’s Day Dream: Prologue”. Mark it as active and head to the quest location. This will take you to a pier just outside the Kingdom of Liones, where an NPC looking like a sailor is waiting for you. Interact with him and after a brief cutscene, he will take you to Spray Island.
All Chest Locations in Spray Island
There are a total of eight treasure chests spread throughout Spray Island. Each chest rewards you with Golden Wave Tokens and Star Fragments. While I have put numbers against each chest below, that is only to keep a tab on the total, you can go ahead and loot these in any order.
Chest #1

Beginning from the north, this chest is located just southeast of the Spray Island Banakro.
Reward: x5000 Golden Wave Tokens, x10 Star Fragments.
Chests #2 and #3

Now head towards southwest of the Spray Island Banakro, up until you reach a giant tower. The second chest is near the entrance of the tower beside a set of stairs. For the third one, use a traversal skill like double jump or wall climb to get on top of the tower and spot the chest. You can also just ride your flying mount to the top.
Reward: x5000 Golden Wave Tokens, x10 Star Fragments and x15000 Golden Wave Tokens, x30 Star Fragments.
Chest #4

This chest is located on top of the windmill in the eastern section of the main island.
Reward: x15000 Golden Wave Tokens, x30 Star Fragments.
Chest #5

From the previous location, turn around and climb down the scaffolding to reach the shore. The chest will be beside a pair of palm trees.
Reward: x5000 Golden Wave Tokens, x10 Star Fragments.
Chest #6

For the remaining chests, you can either use a boat or even better, the new Frost Bear Mount to navigate around the water. From the docks, turn west and head straight until you reach a shipwreck. Sway around and climb the ship to find the chest sitting on the deck.
Reward: x50000 Golden Wave Tokens, x100 Star Fragments.
Chest 7

This chest is on another shipwreck, but this time located on the northwest of the main island. Its sitting on a platform behind the deck.
Reward: x50000 Golden Wave Tokens, x100 Star Fragments.
Chest 8

You might find another wrecked ship while travelling to the previous chest, and this is exactly where the final chest is. Navigate exactly to the location shown in the map, and you will find the chest on top of broken piece of wood.
Reward: x50000 Golden Wave Tokens, x100 Star Fragments.
With this out of the way, if you are yet to collect the Icy Frost Bear, and the Dark Abyss Flare that got introduced in the 1.6 update, you might want to get going on those after finding all the 8 chests on Spray Island.
