Ginatz's acid is an acid which is present in the bodies of drowners and drowned dead. Handy for selling to your local alchemist. It is also a useful and abundant ingredient for alchemy at lower levels in the game.
- In Chapter I, an "Old townswoman" will tell Geralt a tale about drowned dead in exchange for food. This conversation results in journal entries for drowners (not drowned dead,) drowner brain tissue, cadaverine, and Ginatz's acid.

- Geralt can loot the bodies of drowners for cadaverine and Ginatz's acid before he has a Bestiary entry for drowners or ingredient entries for those items. However, drowner remains will not contain drowner brain tissue until Geralt has the journal entries.
