The First Descendant Ancestors Module Fragments: How to Get and Use Them

The First Descendant Ancestors Module Fragments are part of the October 1 event cycle, with a limited-time Fragment Exchange available through BB-On in Albion until October 14. Players can dismantle Ancestors Modules to obtain fragments, then spend them on either Ancestors Module Loot III or a module associated with a specific Descendant.

The system gives unwanted modules another purpose instead of leaving duplicates sitting in inventory. The key decisions are how you earn fragments, whether you want the cheaper broad reward or the more expensive targeted option, and making sure you spend what you want before the event shop closes.

How to get The First Descendant Ancestors Module Fragments

You obtain The First Descendant Ancestors Module Fragments by dismantling Ancestors Modules. The October event also includes a one-time Dismantle Ancestors Module Mission. Dismantling one Ancestors Module completes that special mission and awards one Ancestors Module Fragment.

The special mission can only be completed once during the event, but that does not mean you are limited to a single fragment. Nexon explicitly says fragments can be acquired by dismantling Ancestors Modules anytime. The one-time mission is an extra event objective rather than the only source of the currency.

Where to use Ancestors Module Fragments

Take The First Descendant Ancestors Module Fragments to NPC BB-On in Albion and open the limited-time [Event] Fragment Exchange. The shop became available after the October 1 patch and remains open until October 14 at 23:59 PDT.

The timing matters because Nexon distinguishes between earning fragments and accessing the exchange. Fragments can come from dismantling Ancestors Modules, but the October Fragment Exchange itself is only available during the event period. Do not assume you can wait until after October 14 to make the purchase.

Ancestors Module Fragment Exchange prices

There are two main ways to spend The First Descendant Ancestors Module Fragments. Ancestors Module Loot III costs four fragments and gives one Ancestors Module from any Descendant. An Ancestors Module for a specific Descendant costs eight fragments. Nexon lists both options with unlimited trade counts during the event.

The four-fragment option is cheaper and draws from the wider Descendant pool. The eight-fragment route costs twice as much but narrows the result to the Descendant you choose. That makes the best exchange dependent on whether you want more attempts or more control over whose module you receive.

Should you spend four or eight fragments?

Players developing several characters may get more mileage from spending four The First Descendant Ancestors Module Fragments on Ancestors Module Loot III. Two four-fragment exchanges cost the same as one targeted eight-fragment exchange, although the broader pool means either result can belong to a Descendant you are not currently building.

If your priority is one character, the eight-fragment exchange is easier to justify. It does not guarantee a particular named module, but selecting the Descendant removes unrelated character pools from the choice. Check the shop description before confirming so you understand exactly what the selected reward contains.

Can exchanged modules be returned?

Nexon says rewards purchased with The First Descendant Ancestors Module Fragments cannot be returned or exchanged for another reward. That makes the final confirmation important, particularly when spending eight fragments on the character-specific option.

Unlimited trade count does not mean purchases are reversible. It only means the shop does not impose a small fixed purchase cap on the listed options. Make sure you have selected the intended Descendant before spending a larger fragment balance.

When does the Fragment Exchange end?

The shop for The First Descendant Ancestors Module Fragments ends October 14, 2026 at 23:59 PDT. Nexon’s general event precautions also state that an event can end when maintenance begins if maintenance takes place on the final day.

Spend planned fragments before that final window rather than treating the deadline as extra inventory storage time. The event shop is accessed through BB-On in Albion, while the wider October event details are also visible through the Event interface and Descendant Mission Board.

How the fragment event fits with free readjustments

The First Descendant Ancestors Module Fragments are available during the same period as Today’s Readjustment Benefit, which gives one free Ancestors Module readjustment each day. The October cycle also includes two weekends with a 50% readjustment material discount.

A practical loop is to dismantle modules you genuinely do not need, use fragments on a worthwhile exchange, then reserve the daily free readjustment for a module you plan to keep. That connects the event systems without encouraging you to dismantle useful modules merely to chase more exchange attempts.
