Rupture: who ruptures
Who can take the ruptured form, and what stays outside it.
reviewed 8 August 2026
What it is
The ruptured form belongs to the Edge Case, and to it alone. The Order spent years trying to fit the Edge Case into the Chain and never managed it — it was already a rupture, dressed as a species. What the Order calls rupturing is what happens when it forces what never fitted. Every other esva stays outside: the Reagent finds no way into it.
How I do it
Before you startBeing an Edge Case Only an Edge Case ruptures. That is the single entry point into the ruptured form.requiredFree apparatus slot The reagent takes the slot. If an apparatus is equipped, remove it first.required
How to read the gate before equipping:
- Read the esva's recordIn the party, open the esva and see what it is. Only the Edge Case takes the ruptured form.in gameParty → esva
- Free the slotIf an apparatus sits in the slot, take it out. The slot is single and the reagent will take all of it.in gameParty → esva → Apparatus
- Equip and checkWith an Edge Case and a free slot, put in the Rupture Reagent. The ruptured form comes at once.in gameParty → esva → Apparatus
What I get — and what it costs
What I get
Ruptured form openedAn Edge Case with a free slot starts fighting in the ruptured form, and returns to normal when the reagent runs out.Only with an Edge Case and a free apparatus slot. Outside that, the reagent does not take.
What it costs
Deviation never rupturesRupture and deviation are mutually exclusive branches. A deviation esva does not take the ruptured form, reagent or no reagent.Every other esva stays outsideRupture belongs to the Edge Case alone. In any other species the reagent finds no way in.One slot, one choiceWhile the reagent is equipped, the esva carries no apparatus.
