Upon arrival the player is alone and free to explore the island. Certain NPCs and Origin characters from the ship can be found and react to the player based on how the player behaved toward them previously. Up to three party members can be recruited and there is no shortage of side quests or other activities. How the player behaves towards the party members and other people around influences the attitude they form toward the player, and if they find the player particularly unpleasant they may leave the group outright. All Origin characters can be recruited but only three may be in the party at any time so players are encouraged to swap out members and see who is the best fit based on combat attributes and personality.

The tag system is a new feature introduced in this sequel, which allows specific dialog options to become available based on gender, race, profession, and origin story. New tags may be gained and current tags may be lost based on character decisions and achievements. Should the player choose to design a character without an origin story, they will have the choice to add extra tags during the creation process to help personalize the experience by giving the character a unique personality and dialog options. There are presets that allow a character to begin the game better suited for a play style fitting a traditional RPG class such as warrior or rogue but there are no character classes, allowing the character to be customized and built as they progress through the game however the player sees fit. The multiplayer limit has been raised from two player to four player, and players may be in direct conflict with each other during certain quest goals based on origin story, making it a spur of the moment decision to play cooperatively or competitively. There is also the new dynamic music system where the player selects a character's chosen instrument, allowing this instrument to take lead in the soundtrack during crucial moments of combat or story development.

Creating a Lockpick is a quick and easy recipe that requires a Hammer and Nails. While this produces only 4 Lockpicks, the Hammer isn't consumed during crafting and remains in the player's inventory. As long as the player has nails, they have an unlimited source of the item. Players can also craft Lockpicks using Soap and a Key. Much like the Hammer, the crafting process does not consume Keys. If the player has two Needles, their combination will also result in a Lockp

The world in which Divinity Original Sin 2 exists is called Rivellon. In this reality, all living creatures are made from an energy called Source. Some people of Rivellon are capable of tapping into Source to improve their abilities in fighting or to cast spel

There are many treasures and interesting hidden encounters on the island and a good portion will be missed if the player is fixated on only solving the quest that is supposed to lead to the escape from Fort Joy. Original Sin II gives the player a lot of freedom in regards to their play style and how they want to interact with NPCs, but remember that every action carries its own consequence. During the review play through, Fane started peaceful and diplomatic with all magisters and other NPCs lurking about Fort Joy and always sought a non violent solution for each encounter, that is until one particular incident happened. A cat had decided to follow us, and even thought with the Pet Pal talent he didn't speak very much he was a friendly companion. During some exploration of Fort Joy Fane and his companions came near a locked gate, they weren't causing any trouble and guards told us to step away. As we started to take our leave a guard shot an arrow at the cat without provocation killing it instantly. These guards then saw a display of poison and fire that left their charred, broken corpses arranged in a display that would make John Wick proud. A well timed autosave from not even five minutes prior allowed for a load where the feline companion was back good as new, but this time Fane was getting on the other side of that gate, and these same guards were preemptively killed again before they could bring any harm to the cat. This had a slight impact in how the magisters viewed us in town, so from this point on the play shifted to a much more aggressive style that was intolerant of magisters.

Instead of being limited to being human, Divinity: Original Sin II gives the player the option to also be an elf, dwarf, lizard, or undead, though that last one which is personally the most interesting option is not presently available in the Early Access build. There are also optional origin stories that the player can use for their character, four are currently available but more will be included in the final release. Origin stories not selected by the player will be seen in NPCs met during the game that could join the party. These different origin stories add an extra dynamic to both single and multiplayer modes. Not all characters will have the same objectives they want to achieve, which can lead to some conflicts. With their being freedom to play the SLG game Guide any way a player decides, how conflicting goals among party members are addressed is entirely up to the player's imagination. This can be even more interesting in multiplayer, especially since the option to have four players simultaneously is now included. Playing with three other people who all have conflicting objectives can elevate the role playing element beyond what can be achieved in most video game RPGs.
