"Legends of Runeterra" is a free-to-play digital collectible card game (CCG) developed and published by Riot Games. It is set in the universe of "League of Legends," Riot Games' highly popular multiplayer online battle arena (MOBA) title. "Legends of Runeterra" was designed as a separate game, but it shares the lore and characters of the "League of Legends" universe. "Legends of Runeterra" offers a strategic card battle experience where players build decks using a wide range of champions, followers, spells, and landmarks from the "League of Legends" universe. The game is played in 1v1 matches against other players, and the objective is to reduce the opponent's Nexus (health) to zero. Regions: The game features several regions, each with its own unique set of champions, spells, and playstyles. Players can build decks using cards from one or multiple regions. Champions: Champions are powerful cards that come with unique abilities. They level up as certain conditions are met, becoming even more potent. Mana System: Players gain mana each turn, which they can use to play cards. The mana system ensures that matches progress strategically and that players must make choices about which cards to play. Spell Mana: Spell mana is a separate resource that can be banked to use on spells and abilities. It allows for more flexible gameplay. Attack and Defense: Players take turns attacking and defending. When attacking, players choose which units to attack with, while the defending player decides how to block. Keywords: Cards have keywords that describe their abilities and interactions, adding depth to the gameplay. Examples include "Elusive" (can only be blocked by units with "Elusive") and "Challenger" (can choose which enemy unit blocks it). Nexus Health: Players start with a certain amount of Nexus health, and the goal is to reduce the opponent's Nexus health to zero. Attacking the Nexus directly is one way to win, but players can also win by controlling the board and eliminating the opponent's units. In summary, "Legends of Runeterra" is a highly regarded digital collectible card game set in the "League of Legends" universe. Its strategic depth, engaging gameplay, and generous free-to-play model have made it a popular choice among CCG enthusiasts and fans of the "League of Legends" franchise.
