Help us build Vinterkyla together. This tool captures only the item definition — runtime stats (rarity/level/duration) are handled by the game.

Open Item Builder How it works

Quick tutorial

1) Find the asset on Synty Dex → copy the prefab name & Unity path and take a transparent screenshot.
2) Here, pick Category (and slot/visuals if Armor).
3) Fill the required fields, add to list, then export a ZIP with items.json + images — or submit to server.
