The Heavenly Stone’s Debris is the fourth part of The Chasm Delvers World Questline. It can be initiated by speaking to Jinwu in the base camp after completing The Chasm Spelunkers. She’ll ask you to retrieve gunpowder from the storehouse to make explosives. To do so, you first need to find the two keys to unlock it.

The quest will mark up the two locations of the keys in the World Map and mini-map, so make sure to reference them. The keys can be obtained in any order.

Head to the area circled red in the image above. You’ll find a clearing with some dark mud. Be careful not to step on them, or they’ll drain your Lumenstone Adjuvant’s Energy.

The first key is hidden discreetly inside the pot above the water filtration system. Attack the pot to reveal a glowing Investigate spot. Interact with it to obtain Storehouse Security Key No. 1.

Head to the area circled red in the image above. When you get there, make sure to jump down until you get to the watery area under the Mine. You’ll find some Treasure Hoarders, but you don’t have to defeat them to complete this part. You’ll also find a similar water filtration system to the one in the first area, but the key isn’t hidden there this time.

Turn left to find footprints leading to a suspicious boulder beside the Lumenlamp. Go near it, and you’ll find a sparkling Dig spot. Interact with it to reveal an Explosive Barrel. You need to attack the Barrel to destroy the boulder behind it. It’s highly recommended to use an archer to do this so that you don’t die.

Destroying the boulder will reveal a glowing Investigate spot. Interact with it to obtain Storehouse Security Key No. 2.
