The rules has a separate passage for replenishing cages:
If one of the two cage-buying action spaces is blocked by a neutral imp, you deal only 1 new cage, leaving one pit empty. Apparently, the neutral imp took one cage before you could get there.
- This rule seems to assume that the board starts with one cage and 2 open slots every round: replenish one, leave one open.
- What if the board starts with any other number of cages? We had rounds starting with both 3 and 2 cages. In these cages we would possibly not replenish? Or even remove a cage?
