Dwarven spirit

Dwarven spirit is considered an alchemy ingredient in and thus can't be consumed like regular drinks. It can be used to replenish potions and bombs during meditation if no alcohest is available, and is needed to craft all mutagen decoctions, base-level potions, and a couple of quest item ones.
It can be found as both random and guaranteed loot in many places, received from the merchant in Claywich for rescuing him, or purchased from the following merchants:

* Bram in White Orchard
* Elsa in White Orchard inn during Lilac and Gooseberries
* Gremist at Gedyneith
