Rupture Reagent
What the reagent does, where it comes from, and what it takes up on the esva.
reviewed 8 August 2026
What it is
The Rupture Reagent is a generic apparatus: one single reagent serves all 13 classes. It occupies the esva's apparatus slot and unlocks the ruptured form in combat.
How I do it
Before you startA completed Cavern the reagent comes only from the Cavern; no other activity delivers it.requiredA free apparatus slot the esva needs a vacant apparatus slot to take the reagent.required
How to get it and how to put it to work:
- Close a Cavernthe Cavern is the reagent's single source.Incursion Map → Cavern1 cavern per day, per person
- Slot the reagent into the esvaopen the esva and put the reagent in the apparatus slot; the slot takes one apparatus at a time.Collection → esva → apparatus
- Rupture in combatwith the reagent slotted, the ruptured form becomes available during combat.
In development
What is missing: whether the reagent is consumed on rupture and how many esvas can carry it at the same time.
What already holds: it is generic, comes only from the Cavern, occupies the apparatus slot and unlocks the ruptured form in combat.
What I get — and what it costs
What I get
