Look for the Other Origin Characters
Divinity: Original Sin 2 Beginner’s Tips
Once you’ve picked an Origin Story, the Origins that you didn’t pick will become available as party members in the world that are available for recruitment. While you won’t have access to their personal quests, you can still recruit them and control them if you wish. Once you’ve located all of the Origin characters available in the game, make sure to talk to every NPC in the game to see how they react to your different party members. Some Origin characters might be better equipped to persuade a stubborn NPC than your own character is, so I advise swapping between them every now and then.
Having all these characters with differing personalities in one party can also create conflict, so make sure you manage their needs and priorities accordingly while you’re adventuring in Divinity: Original Sin 2.
You can only have a total of four characters in your party as well, but don’t be afraid to leave someone behind if you need to make room for a mage or some other class that you don’t already have.
