If I'm a level 5 year old human, I can pull the trigger on a machine gun just as well as a level 50 year old. I don't understand level requirements on weapons. Not sure if this was fixed in that version, but be careful. Also, I'm playing the classic version, since I was well into that before the definitive version came out.

It wasn't until I went to steal more stuff that I realized something was wrong. In case you're wondering how I didn't notice, I usually play that character as a ranger. I consider this a serious bug in the game. This is painful, and I'm having to replay some of the game now that involved a good deal of fighting, exploring, and rare vendor finds. It did, but it also randomly used my most valuable daggers and produced a stupid 'basic sword' as a result! I didn't realize it until much later, and it took much restoring into save games to discover the root cause. I had a bunch of common knives I had picked up and thought the process would use those. Don't blindly craft a 'Knife on a stick' using the recipe interface. Weapon Recipes in Divinity: Original Sin 2 are the formulae for crafting specific Weapons within the game from Materials you happen to gather.
