Sanctum: Vigilant Eyes is a solo puzzle dungeon in Russet Highlands built around Sealed Aniimo Helgon's Bilateral sight and the Gravity Pull player skill. Here's where to find it, how to solve its puzzle, and where to find all three hidden chests.
Where to Find Sanctum: Vigilant Eyes
Sanctum: Vigilant Eyes is located to the right of the East Teleporter Bloom in the Russet Highlands region.

Sanctum: Vigilant Eyes Objective
The sanctum's objective is to reach its heart and restore the Vein. Beyond that objective, the sanctum also hides 3 chests.

Sanctum: Vigilant Eyes is a solo challenge. You don't need to team up with another player to enter.
How to Solve the Vigilant Eyes Puzzle
The puzzle in Sanctum Challenge: Vigilant Eyes centers on the player skill Gravity Pull together with Sealed Aniimo Helgon's Bilateral sight, which unlocks walls (including draining water). A combat skill, Wind Tackle, is also used to break cracked walls.

The player skill Gravity Pull unlocks at II Student rank. Make sure you've unlocked it before entering the sanctum if you want to claim every chest.
Chest Locations in Sanctum: Vigilant Eyes
- Chest 1: after the first Totem, drain the water with Bilateral sight
Turn right after the first Totem and use Helgon's Bilateral sight to drain the water. Jump down to obtain the chest.
- Chest 2: between the 1st and 2nd waterfall
After clearing the first Ball Socket puzzle, head towards the four waterfalls and look downwards to see an entryway between the 1st and 2nd waterfall. Enter it and clear the puzzles within to obtain the chest.
- Chest 3: after the last puzzle, before the exit cube
Chest 3 is obtained after the last puzzle, right before the exit cube.
Repair the Vein and Claim Your Reward
Once you've collected all three chests, head to the end of the sanctum and interact with the cube to repair the Vein, which awards Lumin Amber x1. Clearing the sanctum for the first time also awards EXP x500.
