Companions in your party are fully playable, and will potentially have different interactions with the environment and NPCs than the player character.
They can recruit up to three companions to assist them although mods in the Steam Workshop exist which increase the maximum number of party companions. Unlike the original game, players are also given the possibility to create an undead character of one of the available races. Players are also able to create a custom character and choose their stats, race, gender, and origin story at the start of the game.
Several pre-made characters with backstories are available to the player. As with Divinity: Original Sin, players can play solo or with up to three others in their party.
