Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Game Master Flexibility in Characters' Starting Stats

Yo @Enigmaze there are a couple of scl vets around indeed
1: All PCs must be on the same map. I am not sure about spawning locations, but you could always pause the game and seperate the party.
2: You can do anything you like with or to characters and that includes giving or taking equipment and skills.
