How to Get Ultimate Hailey in The First Descendant starts with Cradle of Evolution, because Nexon has tied Ultimate Hailey directly to the new dungeon rather than hiding her behind an unrelated event. The important drop is Amorphous Material Pattern: Ultimate Hailey, which can be earned from mission completion and is the route to the Research Blueprint needed for her crafting process.
The useful part of How to Get Ultimate Hailey in The First Descendant is that Update 1.4.3 gives an exact source and an exact mission-completion chance. You are not farming every activity in the game hoping for a vague Ultimate component. Cradle of Evolution is the activity to target, and Hailey’s new story also feeds the same progression loop with Phase-Tuned Crystals.
How to Get Ultimate Hailey in The First Descendant: farm Cradle of Evolution first

Nexon lists Amorphous Material Pattern: Ultimate Hailey as a 25.7% mission-completion reward from Cradle of Evolution. For How to Get Ultimate Hailey in The First Descendant, that makes repeated Cradle clears the central farming route. The dungeon unlocks at Mastery Rank 18 and can be entered through Tactical Transport Control in Albion or from the World Map.
Public Operations require 81,580 Arche Activity, but Private Operations remain available below that recommendation. That matters if your character is ready to start farming but has not yet reached the public matchmaking threshold.
What the Ultimate Hailey pattern gives you
The patch notes say the Research Blueprint required to craft Ultimate Hailey is obtained through Amorphous Material Pattern: Ultimate Hailey. In other words, How to Get Ultimate Hailey in The First Descendant is not simply a shop purchase guide, even though Ultimate Hailey is also sold through the in-game Shop. The farmable route is built around the pattern and the normal Research process.
Nexon does not turn the patch notes into a complete Research screen dump, so check Anais and the live Research Institute for any final material totals, Gold costs and timers shown on your account. The important confirmed part is where the new Blueprint route begins.
Use Hailey’s Descendant Story for extra crafting material
Equipping Hailey or Ultimate Hailey activates Hailey’s Descendant Exclusive Quest. Completing the full quest line awards 100 Phase-Tuned Crystals, one Crystallization Catalyst, the Shattered Scope chest attachment and the Sniper Squad Photo Lounge ornament. Those Crystals make the story worth doing while working through How to Get Ultimate Hailey in The First Descendant.
Because the story is tied to having Hailey equipped, it is sensible to clear it with normal Hailey while you are still working toward Ultimate Hailey. That turns story progress into useful Ultimate crafting material instead of leaving the quest until after the new Descendant is already finished.
Ultimate Hailey also has two Cradle modules
Cradle of Evolution can also drop Dangerous Distance and Extreme Strike, the two Transcendent Modules exclusive to Ultimate Hailey. Each module is listed at a 17.1% mission-completion chance. They are not the Research Blueprint itself, but they are part of the same farming route and make How to Get Ultimate Hailey in The First Descendant more efficient if you want her launch-day kit rather than only the character unlock.
Dangerous Distance is the close-range option, while Extreme Strike is designed around distant targets and long-range Chill damage. Keeping those module drops while farming the Ultimate Hailey pattern avoids having to return later for the pieces that define her two new playstyles.
Can you buy Ultimate Hailey instead?
Yes. Update 1.4.3 adds Ultimate Hailey and Ultimate Hailey bundles to the Shop. That gives How to Get Ultimate Hailey in The First Descendant two routes: farm Cradle of Evolution and Research her, or use the Shop where the product is available in your region. Nexon notes that some products may not appear in every country because of service availability and local regulations.
For players who prefer the farmable route, the pattern chance, story rewards and module drops make Cradle of Evolution the obvious place to spend time after the update.
That keeps How to Get Ultimate Hailey in The First Descendant tied to the actual Update 1.4.3 rules rather than older pre-patch assumptions.
For How to Get Ultimate Hailey in The First Descendant, the live tooltip and the published Update 1.4.3 values should take priority over older builds and guides.
