Magicka in The Elder Scrolls: Legends is the basic resource in every battle. Every card costs magicka to be played.
Players who start second start with the support item, Elixir of Magicka, which increases their current magicka by 1 and can be used once per turn for up to three turns. This was replaced by the Ring of Magicka.
Magicka increases by 1 on each player's turn, maxing out at 12 maximum magicka, but some cards can make it go higher than 12, such as Tree Minder—it does not matter if one does not already have 12 magicka when Tree Minder was played, it will still go to 13 when 12 total turns pass.
- There is an achievement called "Hist Mage" that requires the player have reached 15 max magicka in one game.
