Magna Carta: The Phantom of Avalanche is a Korean-made role-playing game with Japanese-style gameplay mechanics and aesthetics. Enemies attack randomly, and battles are turn-based. Characters can move across a confined battlefield during combat. Movement, spells, and attacks cost turn points, which the characters are given each turn. Characters can execute ability attacks which deplete their TP bar, as well as perform powerful combos that require the player to press keys in certain rhythmical patterns.
Carta points are awarded for defeating foes. Carta are energy patterns that roughly correspond to elemental magic and are represented by Chinese characters, The player can distribute carta points freely to many characters attributes which affect their spells, range, attack and defense. The system is somewhat similar to the junctioning of Guardian Forces in Final Fantasy VIII.
