PoxNora: Battlefield of the Immortals is a multiplayer online game that combines a collectible card game with a turn-based strategy game. The game is free to play with "Sample Battlegroups" and players can purchase additional game pieces, called "runes", and build their own strategies. Players command armies of fantastic creatures, cast spells of devastating power, and summon relics and equipment of ancient renown in order to defeat their opponents. These creatures, spells, artifacts and equipment are represented by Runes - items of magical power that, when activated, come to life on the battlefield. Each Rune type has its own set of traits. Some traits, like Nora Cost and Cooldown, are common to all Rune types.
