Alchemy (Skyrim)

An alchemist can create magical potions and deadly poisons.

Alchemy is one of the 18 skills in The Elder Scrolls V: Skyrim and falls under The Thief play-style. As such, alchemy is The Thief's crafting skill as opposed to The Warrior's Smithing and The Mage's Enchanting. Alchemy allows player to make more potent potions and poisons. This is accomplished at an alchemy station or lab, in various locations throughout the game - unlike previous games in the series, the player does not need to carry the alchemical equipment to make potions, but must visit such a lab. Labs are generally located in alchemy supply shops, private studies and occasionally inns. Each possible ingredient in Skyrim has four properties. These are unknown until the player either individually eats ingredients or successfully mixes a potion or poison. {C}Governing Guardian Stone: The Thief & The Lover Stone

Leveling up Alchemy
Alchemy increases proportionally to the cost of the potion being brewed. Cost of the potion depends on its effects. Potion with multiple effects costs more (effect costs are additive, even if the effects themselves do not mix well, such as "Damage Health" and "Restore Health"), and different effects have different costs (for example, "Slow" effect costs a lot, while "Damage Health" is very cheap).

Alchemy Ingredients
Ingredients can be found all throughout Skyrim. Each has four different effects which can be discovered by attempting to brew a potion/poison with two or more ingredients sharing an effect. The first effect can also be found by 'eating' the ingredient, which causes the effect on the player after consumption.

Recipes
Some Alchemists sell potion recipes, such as Nurelion at The White Phial or Babette inside the Dark Brotherhood sanctuary, which helps limit the experimentation process. Once those recipes have been purchased, the Alchemy Lab acknowledges the player that they can make the new and unknown potion only if they have acquired all necessary ingredients beforehand.
