I put the word reasonable for a reason. Of course you can make clams cost 65 water and 40 nature, but nobody will make them then. I meant that I don't think it's possible to balance them by ajusting the cost, they are either too powerful or useless, because of their mechanics. The only real solution is to limit their maximum number, but the only way to do it without house rules is to make them unique.
