PoxNora: Battlefield of the Immortals is a multiplayer online game that combines a collectible card game with a turn-based strategy game in a fantasy setting. PoxNora was originally launched via Java Web Start through a browser and can be played on Microsoft Windows, Mac OS X, and Linux.
Players build decks, called “Battle-groups”, on PoxNora’s website. A Battlegroup consists of thirty runes in any combination of spells, relics, equipment and champions. The game is launched via Java Web Start and players enter one of four game lobbies where they can chat or enter games. A fifth game lobby is reserved solely for trading discussion. Games consist of two players, though matches against AI “bots” are possible now with the release of single-player campaigns, first introduced in the “Path to Conquest” Expansion.

The game is free for trial play, but to be able to upgrade runes, or to trade for other runes, it is necessary to purchase runes. Every booster pack has a set number of rarity slots. The premium subscription gives access to Premium Campaigns, store discounts, the possibility of being allowed the privilege of beta testing upcoming expansion runes, the ability to “craft” runes by sacrificing other runes using “crafting recipes”, and the ability to obtain a few “Limited Edition” runes that otherwise do not appear in purchased packs.

PoxNora’s world is split among eight factions. Each rune belongs to a particular faction. Players receive bonuses if their Battlegroups have at least 15 runes of a given faction and a greater bonus if all 30 runes are from the same faction. An additional Shrine Bonus is activated by having 15 runes of a faction.
