Rupture
What Rupture is, how a normal esva takes the ruptured form, and how to undo it.

What it is
Rupture is a combat transformation: the esva equips the Rupture Reagent in the apparatus slot and takes the ruptured form while it carries it. It exists to give the same esva a second combat form — it is not a new specimen and not an evolution stage.
How I do it
Before you startRupture Reagent in the collection The Cavern is the only source of the reagent. Without it, no esva ruptures.requiredFree apparatus slot The reagent takes the esva's single slot. If an apparatus is already there, remove it first.required
Step by step to put the ruptured form on and take it off:
- Take the reagent in the CavernThe Rupture Reagent comes from the Cavern and from nowhere else. It is generic: one reagent serves all 13 classes.Incursion Map → Cavern
- Open the esva and check the slotIn the party, open the esva and look at the apparatus slot. It has to be free.Party → esva → Apparatus
- Equip the reagentPut the Rupture Reagent in the slot. The esva takes the ruptured form at once and holds it while it carries the reagent.Party → esva → Apparatus
- Remove it to go back to normalRemove the reagent and the esva returns to its normal form. The reagent is not consumed: it stays available to use again, on that esva or another.Party → esva → Apparatus
What I get — and what it costs
What I get
Ruptured formThe same esva fights in the ruptured form while it carries the reagent. The reagent is generic — one for every class — and is not consumed when equipped.It holds while the Rupture Reagent sits in the slot. The reagent comes from the Cavern and from no other source.
What it costs
You give up the apparatusThe slot is single. With the reagent in it, the esva carries no apparatus.A ruptured esva is not containedThe ruptured form is not a containment target.It does not enter as a new specimenRupturing creates no specimen and advances no stage: it is the same esva, with a second combat form.
