I am writing a module in which I have placed a door behind the encrusted detritus of bivalve mollusks (e.g. oysters), so the door is locked, but also jammed or fastened shut.
My proposed course is: adventurers can unlock the door by Criminal, but then it doesn’t open; they can break free the encrusting by Stonemason, but then it is still locked; they can break free the hinges by Sapper, but it is still encrusted.
So, I do not mind that there are two turns at stake, the door requires two of three options: unlock and break free OR unhinge and break free.
Does it seem that Sapper should cover the role of breaking it free from encrusted detritus, or is it appropriate to use Stonemason?
