Flasks
What the flask does, what changes between tiers, and what each throw consumes.
reviewed 8 August 2026
What it is
The flask is the apparatus that closes an esva's containment at the end of combat. There are flask tiers: each tier carries its own charges and a containment chance higher than the tier below.
How I do it
Before you startA charged flask in the party A flask with no charge makes no throw. Check before entering.required
The flask is prepared at the Post and used inside the Cavern.
- Stock up before leavingAt the Order Store, buy flasks with Crédito and leave them in the party.in gamePost → Order Store
- Pick the tier by the targetA higher tier raises the containment chance. Keep the high ones for the esva you want in the collection.in gameParty → Flasks
- Throw at the end of combatWith the esva weakened in the Cavern, use the flask. Each attempt spends one charge, containing or not.in gameIncursion Map → Cavern
- Check the collectionA closed containment sends the esva to the collection. Check before assembling the party again.in gamePost → Collection
In development
What is missing: the flask price ladder, each tier's containment chance, and the number of charges per tier
What already holds: that flask tiers exist, that each tier has charges, and that the containment chance rises with the tier
What I get — and what it costs
What I get
Flask, by tierthe apparatus that closes containment and sends the esva to the collection, with a higher chance as the tier risesThe flask is bought with Crédito and each attempt consumes one charge, with or without containment.
What it costs
Every attempt spends a chargeThe charge leaves on the throw, even when containment fails.Tier does not guarantee containmentA higher tier raises the chance; no tier closes containment every time.
