Infinity Spell Card is a free to play MMORPG which features countless classes and races for the player to master. In Infinity Spell Card, the player is not bound to a single class or race of their choice. Instead, they can create a Team composed of much different class character from all sort of different races.

There is no level or stats increase for any of the characters. The player must utilize each of their character's strong point to efficiently win battles. Winning battles against field monsters, dungeons and doing quest will reward the player Command XP and Levels. As the player's Command level increases, they can recruit more character into their Team.

Having a larger Team doesn't necessarily make the player stronger. If the amount of characters in the player's Team surpasses what the player is capable of controlling, the player's Command level will decrease. Sometimes a smaller Team may be more efficient than a larger Teams.

Other than the character's default skill sets, there is also a Spell Card system. In fact, all of the character's ability are called Spell Card. Which means that other than the race and class unique abilities, most of the character's ability can be switched with Spell Card that the player collects throughout their journey in Infinity Spell Card.
