Launch Tyana Pass Mirror Defense.
Identify Rania’s and Belric’s crystals and defend both as the round progresses.
Collect Citrine’s Remnants when visible to gain additional alternating fragment currency.
Complete the round successfully so both crystals are protected and fragments are awarded.
Repeat rounds while you still need the required fragment types.
Travel to the Necralisk and speak with Otak.
Choose the planned Arcane, such as Arcane Steadfast or Arcane Double Back, and exchange the required fragments.
Return for another round only if the remaining shop balance still requires it.

Otak’s fragment shop is a direct acquisition path alongside the node’s reward table.
Collecting Remnants matters because they can add fragments beyond the round reward.

Repeatable through complete Mirror Defense rounds; keep track of each fragment type because the reward uses separate currencies.

Protecting one crystal and neglecting the other; complete rounds require defending both.
Skipping Remnants while seeking extra fragments; gather them during the defense.
Farming without checking fragment prices; set a clear exchange target with Otak.

Stop when Otak’s displayed cost for your chosen item is covered and the purchase is complete.
