Just about to start this, anyone got any useful tips for me? It's my very first time playing a Divinity game.
Get one rank in Thievery for at least one character, but the more party members that have it, the better (long story short, you can only steal a certain amount of stuff from each NPC with one character, but it's per character, so 2x thieves means 2x stolen loot). Stealing is OP as
fuck in this game.
Play on Classic. The game is hard, very hard at times, but manageable. Only drop it down to explorer if you run across a fight you simply don't seem to be able to win, but have to, for some reason. You can change between explorer and classic whenever you want to, even mid-fight.
Up the quick save limit to 25 and save often. OFTEN. You never know what'll happen next.
Use the environment to your advantage; if you can't beat a fight the first time think of how to bend the environment to your favor (creating chokepoints, laying down oil barrels, assume the high ground for your ranged/casters, etc.)
In addition to this, you can move your characters to better spots before the fight triggers, so you won't start every single fight with your party clumped together. Especially so if it's an enemy that talks to one of your characters before the fight starts - you can move your other characters freely while the one unlucky character is talking to the enemy, keeping them busy.
