Potions

Potions can be found, purchased, or created. You can create potions at an Alchemy Lab using ingredients you have collected in the world. See the Alchemy section for details.
Potions that restore Stamina or Magicka should be used during combat, to increase the number of available spells and power attacks.
These potions are available from the standard potion leveled lists; the level at which each first appears is provided in the table.
