Seriously, what's up with Larian and surfaces? I'd prefer an extra 1d8 dmg. Also, there's a bug with this spell in that it doesn't show up under 2nd lvl spells in your spellbook, but you can upcast it nevertheless
I remember vividly the beginning of EA when even cantrips created surfaces. We are a lot better off now.
Apart from that mobs still have too much "surface" arrows and vials. Every goblin that is no caster throws alchemists fire or somesuch around....
