I hope that elemental combos are toned down and do not dominate the game.
I have never played a D&D game where your bow turns into a magic flaming bow when you throw it into the fire.
When you use a shocking grasp cantrip that does 1d8 lighting damage single target it does not suddenly turn into 10d8 damage when 10 lizardmen stand in a puddle or pool.
I am not one of the BG3 is DOS3 complainers but I still hope we get some hardcore difficulty modus where all those are disabled.
