In Runebound it seems that when you run out of parts for most things you will just find some sort of replacement counter to use for that space, adventure jewels being the only exception. Now I have played many games and if things are playing right there is really only one thing that our play group runs out of and that is level tokens. To go around this I would often just say put an exhaust token on the counter that needs that additional level.
Now this would not be an issue normally, but I noticed that the melee counters double each of the other counters in number. This probably means that melee is "expected" to be picked twice as much, or the level counters are parts limited and we have been playing it wrong. So I guess my question is, are the level counters parts limited?
