Sanctum: Electric Flow is a challenge dungeon hidden in a valley in Blitzwood, built around a Gravity Pull and lightning circuit puzzle with your Sealed Aniimo. Here's how to find it, solve its puzzle, grab every chest, and restore the Vein.
Where to Find Sanctum: Electric Flow
Sanctum: Electric Flow sits in the middle of Blitzwood, southeast of a Teleporter Bloom, tucked into a valley. Track it on the map, and look for its telltale purple light effect to spot the entrance.

Sanctum: Electric Flow Objective
The Sanctum Challenge objective shown in-game is to reach the heart of the sanctum and restore the Vein.

Beyond that objective, there are 3 hidden chests scattered around the sanctum, tracked as Chests Obtained on the challenge screen.
How to Solve the Electric Flow Puzzle
- Unlock Gravity Pull by reaching II Student rank before you enter, or you won't be able to reach every chest
The puzzle revolves around using the player skill Gravity Pull to move objects around the sanctum.
It's paired with lightning circuits powered by the Sealed Aniimo, Bolty's, Thunder Tail skill.

Crates come in 2 types: a Conductive Crate that can carry electricity between two nodes on its own, and a Wooden Crate that only conducts once it's been made wet.
If the electricity connection between conductive points won't link up, try repositioning the Conductive Crate.
Chest Locations in Sanctum: Electric Flow
- Chest 1
Located right behind the first Conductive Crate.
- Chest 2
On the wall just past the first Conduit puzzle. Pull it down with Gravity Pull.
- Chest 3
In a room on the right after the Conduit puzzle room. Push the battery across the metal grate toward the port, then pull the chest down with Gravity Pull once it lowers.
Restoring the Vein and Rewards
Once you've collected all 3 chests, head to the far end of the sanctum and interact with the cube to repair the Vein.

Restoring the Vein for the first time rewards 1 Lumin Amber and 500 Aniimo EXP.
