Barrelmancy

Baldur's Gate III has an abundance of flammable and explosive barrels that can be picked up by the player to turn any area into a minefield with the proper positioning. For instance, Minthara's raid at the Emerald Grove can be trivialized by scattering a bunch of explosive barrels outside the grove entrance, and then lighting them up with a fire-based attack to cause a chain reaction that can kill most, if not all the enemies in the area.
