Aniimo First Spark Sanctum Walkthrough (All 4 Chests)

First Spark is the fire-themed Sanctum tucked into the Breezy Plains area of Nimbus Fields, and it is built around a single borrowed ability. You cannot bring your own team inside, so the whole run comes down to knowing which four objects to set alight and in what order.

Quick answer: Claim Emberpup from the Animo Statue, then aim Fire Bolt at the vine archway, the barrel under the ice block, the chimney bonfire, and the barrel on the high ledge to drop all four chests.

First Spark Sanctum location and entry

The portal sits in Breezy Plains, Nimbus Fields, at coordinates -1018, 0648. The surrounding zone is tuned for Lv. 6-16, and the entrance is a large floating stone cube at the top of a short flight of stairs. Activating the cube opens the portal.

First Spark runs as a Solo Sanctum. The objective line is simple enough: collect chests, reach the depths, and repair the Vein. Finishing it for the first time pays out 500 EXP, 10,000 Credits and 10 Glimmer, on top of anything you pull out of the chests along the way.

Emberpup and how Fire Bolt works

Your own Animo are locked out at the door. Instead, a Sanctum-exclusive Emberpup is sealed inside the Animo Statue in the first chamber, and you awaken and twine with it there. Emberpup’s single ability, Fire Bolt, is what solves every puzzle in the place.

Press E to twine with Emberpup.
Hold Q to enter aim mode, then release to launch the fireball.
Flammable objects such as wooden chests and vines ignite on contact and disappear once they burn through.
The same shot detonates explosive barrels and lights bonfires.

Aim mode exists for a reason. Two of the four chests hang above barrels or bonfires that need a precise hit rather than a snap shot.

Full First Spark route with all four chests

Open the map and set a marker on the First Spark portal in Breezy Plains. Run up the stairs to the floating stone cube and interact with it to open the portal, then step through.

Head to the green waypoint marker on the Animo Statue in the opening chamber. Interact with it to claim the Sanctum-exclusive Emberpup, then press E to twine with it.

A wooden gate blocks the path forward. Hold Q, aim at the gate, and release to burn it away, then walk through once the timber is gone.

In the next area, look up at the stone archway. The first chest is tangled in hanging vines, so put a Fire Bolt into the vines and the chest falls to the floor. Open it for Glimmer, Sparkling Crystals, Credits and a Gargantuan Horn.

Move to the left side of the chamber and go up the stairs. The second chest is frozen inside an ice block with an explosive barrel sitting underneath it. Aim at the barrel and detonate it to melt the ice and drop the chest, which contains Avenging Gear alongside the usual currency.

Head back down and over to the right-hand side, grabbing the blue crystal sitting on the stairs on the way. Follow the painted blue arrow on the wall into the chimney room.

The third chest is stashed up inside the chimney. Hold Q, aim at the bonfire at the base of the chimney, and light it. The rising fire drops the chest, which holds a Marching Flask.

Return to the central room and look up at the high ledge. A second explosive barrel sits next to the fourth chest, so shoot the barrel to blast the chest down and open it for Explosive Gloves.

Run up the central stairs to the high exit, picking up the last blue crystal on the way. Interact with the device at the green waypoint marker to repair the Vein and finish the Sanctum.

All First Spark chest rewards

Chest	Location	Fire Bolt target	Unique item
1	Stone archway, first room	Hanging vines	Gargantuan Horn
2	Left-side stairs	Barrel under ice block	Avenging Gear
3	Chimney room, right side	Bonfire at chimney base	Marching Flask
4	Central room, high ledge	Explosive barrel	Explosive Gloves

Every one of the four chests also pays out 10 Glimmer, 10 Sparkling Crystal and 10,000 Credits, so skipping any of them costs you a meaningful chunk of the run’s value. The two blue crystals on the stairs are worth grabbing in passing but are not tied to the chest counter.

How to confirm 100% completion

The Sanctum tracks your progress on screen with a “Chests Obtained” counter that starts at 0/4. Once it reads 4/4, the game confirms you have collected every chest and directs you to the high point in the central room to leave.

You can trigger the exit device at any point, even with chests still unopened, so check that counter before you touch it. When the Vein is repaired, the first clear rewards land and the Sanctum closes out with all four chests banked.
