There are 3 "specialized" markets in RtL: Forge, Nerekhall and Frostgate.
For example, in Frostgate, the heroes draw treasure cards until they draw an Other item.
Say, they draw 3 weapons and then an Other item.
Can they buy any/all of the 4 cards or just the one Other item?
P.S.: Sorry for posting this in your list of questions thread, Paul Grogan. I'm new here and hadn't fully read your introduction to that thread. Is there any way to delete posts on these forums?
