with 1 caveat. A surface must be as easy (or easier) to remove than it is to apply. .
I hadn't thought of this but I think you're right. Like there was a room full of poison which I wanted to get past. I did what I'd do in Divinity, which is blast it with fire to get rid of it, but that had no effect. I assume they got rid of reactions like that because it would be too extreme for the more subtle nature of these rules, but in a way by being half way in between it actually makes it less manageable.
