Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Lucky Charm and Thieving are gamebreaking.

With lucky charm you'll get a huge amount of powerful magic items.
With thieving you'll get all items NPC are selling/carrying for free, without any problem.
If you do this, you'll get so powerful with gear, that tactician mode become a piece of cake early on (act1) !
