Ori and the will of the Wisps : How to acquire FLASH ability
Table of Contents

Navigating the pitch-black caverns of Mouldwood Depths can be a terrifying experience for players. To survive this hostile environment, unlocking the ori and the will of the wisps flash ability is absolutely essential. This powerful skill acts as both a mobile light source and a defensive tool, making the ori and the will of the wisps flash ability a literal lifesaver. Without it, step out of the light for more than a few seconds, and the encroaching darkness will instantly consume Ori.

In this comprehensive guide, we will walk you through the exact steps required to find this crucial ability, how to manage its energy costs, and how to optimize your build with the best Spirit Shards. Please note that this guide is based on the full game, which is available on the official Ori and the Will of the Wisps on Steam store page. The game's demo does not include the full Mouldwood Depths region or the late-game abilities discussed below.


Understanding the Flash Ability: Mechanics and Costs

The Flash ability is not just a passive light bulb; it is an active skill that must be mapped to one of your three quick-use face buttons. When activated, it projects a radiant aura around Ori. This aura repels the lethal darkness of the Mouldwood Depths, allowing you to explore freely without relying on glowing bugs or stationary plants.

However, this convenience comes at a price. Activating Flash costs half of an energy cell, and keeping it active drains one energy cell every eight seconds. According to player experience, managing this drain is the single biggest challenge when first exploring the depths. Fortunately, the aura also deals passive damage to nearby enemies, ticking for 2 damage units every half-second, which helps clear out minor pests like bats and small spiders without requiring manual attacks.

Attribute Value Gameplay Impact
Activation Cost 0.5 Energy Cell Requires a small initial pool of energy to toggle on.
Energy Drain Rate 1 Energy Cell per 8 seconds Demands constant monitoring; toggle off when in natural light.
Damage Output 2 damage units per tick (0.5s) Acts as a passive area-of-effect (AoE) shield against weak enemies.
Primary Function Illuminates immediate surroundings Prevents the instant-death darkness mechanic from triggering.

To use Flash effectively, players must master the "toggle" technique. Never leave Flash running when you stand under a glowing hanging lantern or near a light-emitting plant. By turning the ability off during these brief moments of safety, you allow your energy cells to last much longer, giving you a wider margin of error during tricky platforming sequences.


Step-by-Step Guide: How to Find the Flash Ability

Unlocking the ori and the will of the wisps flash ability requires traversing the first half of the Mouldwood Depths. Before you begin, ensure you have a decent pool of life and energy cells, as the platforming here can be highly unforgiving.

Phase 1: Entering the Depths and the First Keystone Gate

Upon entering the Mouldwood Depths, you will find the path forward blocked by a locked gate requiring two keystones. The environment is pitch black, and standing in the dark for more than roughly two seconds results in an immediate game over.

  1. Locate the First Keystone: Head to the right from the entrance. You will find a yellow glowing bulb. Strike it to release a temporary light insect. Follow this insect closely as it flies down and to the left. It will guide you directly to the first keystone.
  2. Locate the Second Keystone: Return to the central area and look for a series of yellow glowing plants. You must dash quickly from one plant to the next. Do not linger in the gaps between them. Follow this path of plants as it twists right, down, and then left to find the second keystone.
  3. Open the Gate: Use another light insect to safely navigate back to the keystone gate and insert the keys to open the way forward.

Phase 2: Navigating to the Spirit Well

Once through the first gate, climb upward using the grapple points. You will reach a chamber with a roof blocking the natural light.

  1. Clear the Light Shafts: Destroy the purple corruption bugs blocking the light on both the left and right sides of the ceiling. This will cast permanent beams of light down to the floor, creating safe zones.
  2. Reach the Spirit Well: From the newly lit floor, jump and dash across the dark gaps to the right. Use the jump pads and grapple points to ascend to the upper-right ledge, where you will find a Spirit Well. Make sure to save your game here, as it serves as your primary checkpoint.

Phase 3: Reaching the Spirit Tree

From the Spirit Well, head southwest into the unexplored dark cavern.

  1. Follow the Final Light Bug: Locate the glowing sack on the wall and destroy it to release another light insect. Follow this insect as it travels down and around a series of hazards.
  2. The Final Ascent: The insect will lead you to a glowing jump pad. Bounce upward, grapple to the blue moss walls, and climb up to a large open platform.
  3. Absorb the Light: Interact with the glowing ancestral Spirit Tree at the end of this platform to permanently unlock the Flash ability.

Optimizing Your Build: Shard Synergies for the Flash Ability

Once you have secured the Flash ability, exploring the rest of the Mouldwood Depths becomes significantly easier. However, because of the high energy consumption of this skill, you should adjust your Spirit Shard loadout to maximize your efficiency. Community reports suggest several highly effective builds for this stage of the game.

The Damage Scaling Build

Directly to the right of the Flash Spirit Tree, you can use your newly acquired light to climb up and find a Giant Spirit Light Container. If you navigate west from the flying insects using your grapple points, you can also locate the Spirit Surge Spirit Shard. This shard increases your overall damage output based on how much Spirit Light you currently hold, capping at 3,000 Spirit Light. When paired with the passive damage of Flash, you can melt basic enemies simply by walking near them.

The Infinite Light Build (Community Strategy)

For players who struggle with energy management, the community has discovered a powerful synergy using late-game shards. By pairing the Life Pact shard (which allows you to use Life to cast abilities when Energy is depleted) with Resilience (reducing overall damage taken) and Overcharge (converting excess energy), you can keep Flash active indefinitely. While it still drains resources, the passive health regeneration and damage reduction make the cost negligible.

Shard Name Location Primary Benefit Synergy with Flash
Spirit Surge Mouldwood Depths (West of Flash Tree) Damage scales with held Spirit Light Greatly boosts the passive AoE damage of the Flash aura.
Life Pact Midnight Burrows Uses Life instead of Energy when empty Allows you to keep Flash active even when completely out of Energy.
Overcharge Wellspring Glades Reduces Energy costs, increases damage taken Minimizes the activation and upkeep drain of the Flash ability.
Energy Wellspring Glades Adds extra Energy Cells to your pool Provides a larger buffer of energy for longer exploration runs.

Surviving the Mouldwood Depths: Key Collectibles and Quests

Mouldwood Depths is home to several important items and side quests that are highly beneficial to complete before moving on to the next major region.

The "Breaking the Mould" Quest and Mora Boss Fight

The main quest of this region, Breaking the Mould, culminates in a dramatic confrontation with Mora, a giant corrupted spider.

  • Phase 1: Mora will attack with her massive front legs. You must dash out from under her and focus your attacks entirely on her head. When she fires her giant dark laser, grapple into the air to stay safe.
  • Phase 2: After losing a quarter of her health, Mora will retreat up a vertical shaft. You must quickly scale the walls, using orange lanterns to bash your way upward while avoiding her pursuit.
  • Phase 3: The final arena is pitch black. Here, the Flash ability is mandatory. Keep Flash active to prevent the darkness from killing you, while using its passive aura to clear out the small spider spawns that Mora summons. Defeating Mora rewards you with the "Eyes of the Forest" wisp.

The Tree Keeper Side Quest

While exploring the upper sections of the Mouldwood Depths, you can find a Mysterious Seed. This quest item is located in a western hidden alcove just above the lower keystone gate shortcut. Taking this seed to Tuley in the Wellspring Glades will progress The Tree Keeper side quest, allowing you to grow specialized plants that grant access to new areas.

Additionally, you can find a Moki in need of help in the lower-middle section of the depths. By providing them with a lantern (which requires finding the Moldwood Silk), you will update the Hand-to-Hand trading questline, which eventually rewards you with a map showing all secrets on the world map.


Key Collectibles Checklist

Before leaving the Mouldwood Depths, make sure you have cleared out these valuable upgrades.

  • Splinter Spirit Shard: Located at the far eastern stretch of the upper depths, accessible by gliding right from the main air flow.
  • Life Cell Fragment: Found on a high ledge in the southwestern ruins, requiring a series of precise wall jumps and dashes from a yellow light source.
  • Combat Shrine: Tucked away in the far southwestern corner. Completing this wave-based combat challenge rewards you with an extra Spirit Shard slot. Note that you must pull a nearby underwater lever to open the path to this shrine.
  • Lupo's Map: Located in the eastern-middle section of the depths. You can purchase a complete map of the area from Lupo for 250 Spirit Light, which is highly recommended for finding hidden breakable walls.

Frequently Asked Questions about the Flash Ability

Where is the ori and the will of the wisps flash ability located?

The ori and the will of the wisps flash ability is located at the furthest eastern point of the Mouldwood Depths. Players must navigate through several dark chambers using temporary light bugs and glowing plants, open a two-keystone gate, and reach the ancestral Spirit Tree to absorb the skill.

Does the Flash ability deal damage to enemies?

How do I stop the Flash ability from draining all my energy?

To conserve energy, you should toggle the Flash ability off whenever you are standing near a natural light source, such as a hanging lantern, a glowing plant, or a Spirit Well. Additionally, equipping the Energy or Overcharge Spirit Shards can help mitigate the overall resource drain.

Can I complete the Mouldwood Depths without the Flash ability?
