The Elder Scrolls: Legends is a collectible card game which revolves around turn-based matches between two opponents (player vs. player, or player vs. a computer opponent). The cards are based on creatures, characters and lore found in The Elder Scrolls series. Each player or computer opponent starts with a deck between 50 and 100 cards (previously 50 to 70). At the start of every battle, each player starts off with three cards drawn from that deck and one magicka, which is used to deploy cards. To offset the advantage of taking the first turn, the second player also starts with a jeweled ring in play that can be activated once per turn to gain one additional magicka three times during the game. Each player gets one additional magicka at the start of their turns thereafter. Without use of specialized cards, a player's magicka can only reach 12 in a game. The player and their opponent are represented by a character with a set amount of health, with the goal to reduce the competitor's health to zero.
Each player can use their available magicka to play any number of cards. Cards are divided into four types: Support cards, which provide ongoing benefits; Action Cards, which are effects that are instantaneously played; Creatures, which are the main method of conducting combat; and Items, which enhance creatures. Creatures normally cannot attack the turn they come into play. Creatures have attack and health values; when creatures attack, they deal the damage equal to their attack value to the opponent creature or opponent character, and take damage equivalent to the defending creature's attack. If a creature's health drops to zero, that creature is defeated and removed from play. Many cards feature additional effects, listed explicitly or by a number of pre-defined keywords.
While the main game is free-to-play, expansion sets featuring different themes are available for purchase.
Bethesda announced in December 2019 that development on Legends had been halted, though the game and servers remain available for play.
