A new trivial update has been posted: The Bonerdagon and the Naughty Sorceress no longer destroy combat items when they block them. They just block them when they block them.
We already don't deduct items if your Black Cat or O.A.F. prevent you from using them. This requires similar handling.
Given that you can Funksling two items and either, both, or neither item can be blocked, we'll have to take that into account, somehow.
