Key takeaways

  • Uasnoj Lightroot is in the Lanayru Wetlands Depths, roughly below Jonsau Shrine.
  • Its commonly listed coordinates are approximately 1742, 0018, -0459, although some databases give slightly different values depending on whether they record the centre of the Lightroot or its travel gate.
  • Activating it reveals the surrounding map and unlocks a fast-travel point.
  • The Lightroot is useful for restoring hearts damaged by Gloom while Link is within its light.
  • It has no verified shop, resident NPC, named quest, dungeon, shrine interior or unique reward of its own.
  • The surface location directly associated with it is Jonsau Shrine, not the entire Lanayru Wetlands.

About this guide

Base game scope. This guide covers The Legend of Zelda: Tears of the Kingdom and treats Uasnoj Lightroot as the individual Lightroot location, not the whole Lanayru Wetlands Depths region.

Overview

Uasnoj Lightroot is a Lightroot in the Lanayru Wetlands Depths, the underground counterpart to the surface Lanayru Wetlands. Activating it reveals part of the Depths map, creates a permanent fast-travel point and provides a strong local light source. Its surface counterpart is Jonsau Shrine, located on Mercay Island in the Lanayru Wetlands.

Uasnoj is a relatively small location rather than a settlement, mine, dungeon or quest hub. Its importance comes from its position in the middle of the Lanayru Wetlands Depths and from the map information it provides. The surrounding regional area is much larger and includes other Lightroots, the Lanayru Wetlands Chasm and several separate Depths landmarks. Those places should not be treated as subareas of Uasnoj Lightroot itself.

Location and boundaries

Uasnoj Lightroot stands in the central part of the Lanayru Wetlands Depths. The Lanayru Wetlands Depths is a named regional subarea of the wider Depths, rather than a name for Uasnoj’s immediate platform. Published regional lists identify four Lightroots in this subregion:

That directory is useful for establishing the boundaries of the region, but the three other Lightroots are neighbouring locations, not parts of Uasnoj Lightroot.

Not included

The following are nearby or associated locations, but are separate entries:

The regional location list separately records Lanayru Wetlands Chasm and the four Lightroots, supporting this distinction.

Surface counterpart: Jonsau Shrine

Uasnoj Lightroot corresponds to Jonsau Shrine on the surface. This is part of a broad Tears of the Kingdom mapping rule: Lightroots generally occupy positions directly below surface Shrines of Light, and their names are usually reversed versions of their corresponding shrine names. Uasnoj and Jonsau follow that pattern.

Jonsau Shrine is found on Mercay Island in the Lanayru Wetlands. It is a separate playable location and should not be counted as a structure at Uasnoj Lightroot. The shrine’s trial is Deep Force, and its reward structure belongs to the shrine, not to the Lightroot.

How to reach Uasnoj Lightroot

From the Lanayru Wetlands Chasm

The most straightforward route is to enter the Depths through the Lanayru Wetlands Chasm, then travel southwards through the Lanayru Wetlands Depths towards the Lightroot. Regional guides place Uasnoj Lightroot south of the Lanayru Wetlands Chasm.

Because the Depths are dark before nearby Lightroots are activated, prepare for limited visibility. Brightbloom Seeds, arrows, a flame-based light source or a vehicle-mounted light can make the approach easier.

From an already activated Lightroot

If another Lightroot in the Lanayru Wetlands Depths is active, use the Depths map to judge the direction and travel across the illuminated portions of the region. The most relevant neighbouring regional Lightroots are:

Their coordinates and regional placement are listed separately from Uasnoj.

Using the surface map as a guide

If you are struggling to locate Uasnoj, switch between the surface and Depths map layers. The surface position of Jonsau Shrine provides a strong positional clue for Uasnoj Lightroot below. This is particularly useful because the surface and Depths terrain do not always provide a direct vertical route. The Lightroot-to-Shrine relationship is also useful when checking which Lightroots remain undiscovered.

No story quest, dungeon completion or special ability is required to activate Uasnoj Lightroot.

From an already activated Lightroot

Activating the Lightroot

Approach the glowing root and interact with its central node. Once activated:

Lightroots function in this general way throughout the Depths. They serve as underground equivalents of small mapping beacons rather than as Shrines of Light.

Practical activation route

---

Activating the Lightroot: steps

  1. 01
    The surrounding Depths area is illuminated.
  2. 02
    The corresponding section of the Depths map is revealed.
  3. 03
    Uasnoj Lightroot becomes a fast-travel destination.
  4. 04
    Link can recover hearts affected by Gloom while within the Lightroot’s restorative glow.

Practical activation route

  1. 01
    Enter the Lanayru Wetlands Depths through the Lanayru Wetlands Chasm or approach from another activated regional Lightroot.
  2. 02
    Illuminate the route with Brightbloom Seeds.
  3. 03
    Keep the Uasnoj icon or the surface Jonsau Shrine position as your navigation reference.
  4. 04
    Avoid unnecessary detours into unlit terrain until the Lightroot is visible.
  5. 05
    Activate Uasnoj Lightroot immediately.
  6. 06
    Use the new fast-travel point to return later for exploration, resource gathering or regional completion.

Services and facilities

Uasnoj Lightroot provides only the standard functions of an activated Lightroot.

Not confirmed at this location

There is no reliable evidence that Uasnoj Lightroot contains:

The wider Lanayru Wetlands Depths contains other locations and possible encounters, but they should not be attributed to Uasnoj without location-specific evidence.

Collectibles, items and rewards

Lightroot reward

Uasnoj Lightroot has no separate treasure reward listed for activation. Its benefits are functional:

Nearby resources

The unlit Depths around Uasnoj may contain ordinary regional materials, enemy drops and randomly placed resources, but these should be treated as surrounding Depths content rather than fixed Uasnoj Lightroot collectibles unless a specific map identifies them as part of the location.

No verified fixed chest, unique weapon, armour piece or named collectible is established by the location sources consulted.

Important distinction

Do not confuse the Lightroot with Jonsau Shrine’s reward. Jonsau Shrine contains a Strong Construct Bow and awards a Light of Blessing, but those rewards are obtained in the surface shrine. They are not rewards from Uasnoj Lightroot.

Enemies and hazards

Uasnoj Lightroot itself is not documented as a dedicated combat arena or boss site. The main danger on the approach is the ordinary hazard profile of the Depths:

Community reports frequently mention unusual red-glowing or Gloom-like formations near Uasnoj Lightroot. However, the sources consulted do not establish an official name, purpose, interaction or reward for those formations. They should therefore be treated as an unresolved nearby visual feature rather than a confirmed Uasnoj activity.

Gloom management

If Link’s maximum hearts have been reduced by Gloom:

The Lightroot does not make Link immune to Gloom on the journey towards it. It is safest to mark the location before crossing a long unlit section and to carry enough healing supplies.

---

Gloom management

  1. 01
    Reach the illuminated area around Uasnoj Lightroot.
  2. 02
    Stand within its light.
  3. 03
    Allow the recovery effect to restore hearts that can be recovered.
  4. 04
    Use food or other healing methods for damage not covered by the Lightroot’s effect.

Exploration route and completion checklist

Completion checklist

Efficient first-visit route

  1. 01
    Enter from Lanayru Wetlands Chasm.
  2. 02
    Light only the immediate route with Brightbloom Seeds.
  3. 03
    Follow the approximate coordinates 1742, 0018, -0459.
  4. 04
    Activate Uasnoj Lightroot as soon as it comes into view.
  5. 05
    Check the newly revealed map for unexplored roads, enemy icons and neighbouring Lightroots.
  6. 06
    Compare the Depths map with the surface map and look for Jonsau Shrine above.
  7. 07
    Fast-travel away if your objective was only map completion, or use the illuminated area as a staging point for further exploration.

Lore and naming

The name Uasnoj is the reversed form of Jonsau, matching the naming convention used for many Lightroots and their surface Shrine counterparts. This relationship is one of the most useful pieces of environmental and cartographic design in the Depths: discovering a surface shrine can help identify a hidden Lightroot below, while an activated Lightroot can point towards an undiscovered shrine on the surface.

Uasnoj has no known dialogue, inscription or individual story scene. Its lore significance is therefore indirect. It belongs to the network of Lightroots that make the Depths navigable after the Upheaval and reflects the game’s deliberate connection between the surface Shrines of Light and their underground counterparts.
