The Seven Gods of Rivellon had given up a portion of their collective Source power and infused it into a person, Lucian, known as the Divine, who used his powers to hold back the Void. Living beings on Rivellon have a form of energy known as Source, and individuals called Sourcerers can manipulate Source to cast spells or enhance their combat abilities. The game is set on the fantasy world of Rivellon, centuries after Divinity: Original Sin. The game also features a competitive multiplayer mode, where players are divided into two different teams and fight against each other in an arena map. A skill crafting system allows players to mix and change their skills. The game features both on-line and local multiplayer modes, both competitive and cooperative.

Players are able to split up and individually control their party members, leading to potentially complex battle tactics and role-playing opportunities. 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.
