I allow an Arcana 'stunt' skill check, to modify a spell effect for this kind of improv application. If it sounds plausible but less than automatic ... roll a skill check. If it sounds like it would obviously work, then it just happens. No need to roll.Yeah a lot of it can and already is just improv. I've had AoE cold damage turn water into ice which created an ice hazard that you could fall on long before BG3 or even DOS did that stuff. Setting oil/grease on fire has been a staple as far back as I can remember, though ironically in this new edition they made the Grease spell non-flammable so the exact opposite of what the OP is hoping to see.
