I have to admit that I agree with varangian.
Spells could eventually create a surface (or interract with an element) if we were asking for it but I also want to use all orbs depending the ennemies resistance OR my draconic lineage rather than using the only RAW chromatic orb each time because it ise more powerfull.
I really think that surfaces are a great idea but I really don't like how often it's a thing in BG3 and I particularly fear even more than before level 3 spells.
I really find cool that you can electrify or freeze water surface, that some things can explode or burn... But I'd find more interresting if it was a bit more subtle than "some spells always create surfaces".
To me this things with chromatic orb is a big no.
Eventually as some had already suggested before, let us choose for all spells :
- to target an ennemy = damage but no surface
- to target the ground = surface (to interract with a surface that is already in the environnement, to block a path, to reduce their AC,...).
This would be very cool IMO, increasing the player agency rather than forcing things.
