Beating the enemy adventuring party in the early game got so much easier when I realized there was a way to engage them next to a couple of oil barrels.When I first stated BG3 I had no idea some barrels can explode, it would have meant I could won an encounter instead of having to restart the game due to a save game loop trapping me in the encounter.
These days, any time I see a barrel of any substance, it goes straight to camp.
