Fatal Claw Ability Unlocks and Route Gates
Unlock Fatal Claw's confirmed traversal powers, match each one to its route gate, and recover when an ability seems to be missing.
Direct answer
The confirmed movement unlocks are Mirkam's Sinew from Mirkam, Irbes' Claws from Irbes, and James' Wings after restoring their required pieces. Absorb each defeated boss's power before backtracking.
Quick answer
- Mirkam's Sinew is a forward dash that works in midair.
- Irbes' Claws enable wall clinging, sliding, and wall jumping.
- Restored James' Wings hover on air currents.
- A boss defeat still requires the absorption interaction.

Match each route gate to the right ability
Start with the obstacle in front of Kisha. A broken airborne route calls for a midair movement check, a wall surface calls for wall movement, and an air current calls for restored wings. Doors, one-way breakable walls, and vertical shafts are also confirmed route-gate types, but their exact answer depends on the obstacle and the powers already available.
| What you can see | Ability to test | Confirmed result |
|---|---|---|
| An airborne gap or broken column | Mirkam's Sinew | Kisha performs a forward dash that can be used in midair |
| A wall surface or vertical climb | Irbes' Claws | Kisha can cling to, slide down, and jump from walls |
| An air current crossing a gap | James' Wings | Kisha can hover on the current and move freely while airborne |
| A door or one-way breakable wall | Recheck the visible gate and current powers | These are confirmed gate types, but no single universal power mapping is established for every instance |
The Elord Castle green-card route provides a concrete dash check. Jump toward the broken column, use Mirkam's Sinew in midair, and continue toward the hidden card crate only after landing the crossing.
These powers sit inside the wider first-run progression route. When the obstacle itself is unclear, compare it with the biome edges and return markers in the map and fast-travel guide.
Ability profiles and visual identification
Each movement power comes from a different story entity and answers a different route shape. Identify the source, complete the required interaction, and verify the movement in a safe space before crossing a long hazard.

Mirkam's Sinew
Boss PowerMirkam's absorbed power gives Kisha a forward dash that remains available in midair. It is the direct answer to broken-column gaps and other routes that need extra horizontal distance.
- Source
- Mirkam
- Behavior
- Forward midair dash
- Route use
- Airborne gaps and broken columns
- The boss defeat alone does not finish the unlock; interact with Mirkam afterward to absorb the power.

Irbes' Claws
Boss PowerIrbes' absorbed power gives Kisha a complete wall-movement set. Clinging stabilizes the position, sliding controls descent, and wall jumping converts a vertical surface into a route.
- Source
- Irbes
- Behavior
- Wall cling, slide, and jump
- Route use
- Vertical walls and shafts
- Phase two adds two invulnerable clones; only damage to Irbes lowers the boss-health bar.

James' Wings
Restored PowerJames' Wings are restored from their required pieces rather than absorbed from Mirkam or Irbes. Once complete, they let Kisha hover on air currents and move freely while supported by the current.
- Source
- Restored wing pieces
- Behavior
- Hover and airborne movement
- Route use
- Air-current gaps
- If the hover never starts, check the wing restoration state before retrying the same air current.
Unlock the confirmed movement powers
Mirkam's Sinew
Mirkam appears near the end of Kannir Drilling Site after the conversation with Albus. Finish the encounter, interact with the defeated Mirkam to absorb his power, and then retest a route that needs forward movement in the air.
- Speak with Albus and continue through Kannir Drilling Site until reaching Mirkam near the end of the area.
- Defeat Mirkam, then interact with the defeated boss to absorb the power.
- Return to an airborne gap and test Mirkam's Sinew as a forward midair dash.
Irbes' Claws
Irbes is the main boss of Ashen Valley. During the second phase, dodge the two clones while keeping damage focused on Irbes. Defeat him, absorb his power, and take Irbes' Claws back to a wall route.
- Reach the main Ashen Valley boss encounter and begin the Irbes fight.
- When two clones appear in phase two, avoid them while continuing to damage Irbes.
- Defeat and absorb Irbes, then test clinging, sliding, and jumping on a wall surface.
James' Wings
James' Wings become usable after their required pieces are restored. Toggle the completed wings at an air current. The successful state is a stable hover followed by free airborne movement across the gap.

This focused walkthrough shows the confirmed Mirkam route and reward loop in context. Use it to compare the boss encounter, the post-fight absorption, and the resulting midair movement with your own save.

Confirm the route opened
Treat every blocked map edge as a state check: identify the obstacle, verify the matching power is available, then confirm the route changes after one deliberate attempt.
| Ability | Progress check | Route check |
|---|---|---|
| Mirkam's Sinew | A forward dash activates while Kisha is airborne | The broken-column style gap can be crossed rather than falling short |
| Irbes' Claws | Kisha clings to, slides on, or jumps from a wall | A wall surface or vertical shaft becomes traversable |
| James' Wings | Kisha hovers when the wings are toggled over an air current | The current carries or supports movement across the gap |
If the movement works in open space but the original route still does not change, inspect the obstacle again. A nearby door, breakable wall, shaft, wall surface, or air current may indicate a different gate type.
Diagnose a missing ability or blocked route
Use the smallest reversible check before repeating a long route.
| Expected state | Symptom | Likely cause within the confirmed evidence | Next check |
|---|---|---|---|
| Mirkam is defeated and Mirkam's Sinew is available | The midair dash is still absent | The post-fight absorption interaction may not have been completed | Return to the defeated target and confirm the power was absorbed |
| Irbes is defeated and Irbes' Claws are available | Kisha cannot use wall movement | The boss reward may not have been absorbed, or the tested surface is the wrong gate | Confirm absorption, then test a clear wall surface |
| James' Wings are ready | An air current does not produce a hover | The required wing pieces may not all be restored | Check the wing restoration state before retrying the same current |
| A route remains closed after a valid movement test | The ability works, but the obstacle does not react | The visible obstacle may require a different movement power or approach | Identify whether it is a door, one-way wall, shaft, wall surface, or air-current gap |
After any missing-power check, return to the exact blocked edge that triggered the search. Testing at the original obstacle gives a clear success or failure state and prevents unrelated backtracking.
Use only the confirmed route mappings
The current 1.0 evidence establishes three movement behaviors and one precise route example: Mirkam's Sinew is a forward midair dash, Irbes' Claws provide wall movement, James' Wings work with air currents after restoration, and the Elord Castle green-card route uses the dash to reach a broken column.
The evidence also confirms several broader gate types, including doors, one-way breakable walls, vertical shafts, wall surfaces, and air-current gaps. It does not establish a universal one-to-one answer for every door, wall, or shaft. Use the visible obstacle and the latest confirmed ability behavior together, then judge success by the route change you can observe.
The source fights have their own tells and recovery checks in the complete boss guide. Keep the ability page for unlock and route diagnosis, then move to that guide when Mirkam or Irbes is the actual blocker.
