Elixirs
Main article: Elixirs
Elixirs are a category of consumable that can be crafted from the Alchemy menu or found in the world. Unlike other potions, their effect lasts until a long rest, and you may only have the effects of one elixir at a time.
Note: Some potions in the game are called elixirs without actually belonging to the elixir type of potions. These are listed in this article as any other potion.
