Fatal Claw Progression Guide: First Ending Route

First-Run Route at a Glance

Fatal Claw progression follows an ability-gate loop. Explore the connected regions until a movement barrier closes the current path, earn the matching Mutated Ability elsewhere, then rescan the edge you left behind. The clearest confirmed route transition begins at Elord Castle's large elevator and continues into Kannir Drilling Site after the Eradicator fight.

The route crosses several systems at once. Keep the ability unlock profiles open for obstacle matching, and use the interactive map guide when a newly gained power needs a return route.

Key progression entities and gates

These four profiles explain why each named boss, machine, or survivor state matters to the route. They provide the context behind the steps that follow.

Elord Elevator Eradicator

Route Gate

The intact Eradicator is the combat half of the Elord Castle elevator objective. The green ID card activates the panel, and the boss defeat opens the connection toward Kannir Drilling Site.

Task

Defeat the Eradicator

Kannir Drilling Site opens

Mirkam

Ability Gate

Mirkam waits near the end of Kannir Drilling Site after the Albus conversation. Absorbing his power adds the horizontal midair movement needed for broken gaps and later backtracking.

Power

Mirkam's Sinew

Forward midair dash

Irbes

Ability Gate

Irbes is the main Ashen Valley boss. His absorbed power converts walls from boundaries into climbable routes through clinging, controlled sliding, and wall jumping.

Survivor Quest State

Ending Preparation

Survivor requests are optional world-state tasks that can matter to the assembled ending. Checking them before the first credits reduces uncertainty, while the epilogue remains available for unfinished work.

Follow the Verified Route Gates

1. Explore each reachable region until the next path is clearly blocked by movement or a one-way wall.
2. At Elord Castle's large elevator approach, move right, down, and left to search the wall crate for the green ID card.
3. Return to the elevator, operate it, and defeat the Eradicator to open the connection into Kannir Drilling Site.
4. Continue through Kannir until the Albus conversation, then defeat Mirkam near the area's end to obtain the forward midair dash.
5. When Ashen Valley is your active route, defeat Irbes to gain wall clinging, sliding, and jumping.
6. After every new movement power, reopen the map and revisit the barriers that match it.
7. Before committing to the first ending, finish important survivor requests and deliberate choice-sensitive tasks.

This sequence has an observable end state: the Elord elevator has opened Kannir, both confirmed boss-granted movement powers appear in Kisha's move set, and your selected survivor work is settled before the credits.

Watch the World Route Before You Backtrack

Treat every newly opened movement power as a reason to rescan the map edges you left behind. The map overview below is useful when you need to compare the world's overall shape with a barrier, boss marker, save point, or travel node you remember seeing earlier.

The video is an orientation aid. Your current ability set and the visible state of each gate remain the reliable checks for the route available in your save.

Progress Checks After Each Major Gate

Check the result immediately after each objective. A boss victory without the expected route or movement change tells you exactly which step to inspect before you cross the world again.

If the Map Shows No Unexplored Path

Keep each recovery attempt small and reversible. Confirm one gate, one ability, or one boss state at a time before starting a long backtrack.

What to Finish Before the First Ending

Survivor quests and player choices can affect the conclusion. Resolve the requests that matter to your preferred outcome before committing to the first ending whenever practical. This gives the first credits the strongest chance to reflect the work already completed in that save.

The first credits do not permanently close the route. The epilogue continues afterward, so unfinished exploration and ending work remain available. Use that continuation as recovery space, while treating the pre-credit sweep as the cleaner point for settling important survivor tasks.

The verified quest routes show how a request, item handoff, service reward, and route unlock expose their completion states. Use that same state-checking method for other active survivor work.

Version 1.0 Route Boundaries

This guide covers confirmed Fatal Claw 1.0 progression gates: the nonlinear ability loop, the Elord Castle elevator and Eradicator connection to Kannir, Mirkam's forward air dash, Irbes' wall movement, and the post-credit epilogue. The connected world allows local exploration order to vary around those gates.

When your route differs from another player's path, trust the state visible in your save. Identify the blocked edge, check the newest movement power, confirm the relevant boss or objective, and only then choose the next region to revisit.

For attack tells inside the named fights, continue with the complete boss roster and tactics. The progression page should decide where to go; the boss page should decide how to respond once the arena starts.
