yeah, but fire brands are a lot tougher to make

I think dwarven hammers are worse than frost brands though, seriously how many players that survive a year or 2 in a game don't have at least 1 hammer? They are exceptionally powerful in how much they can save - a hammer probably saves on average at least 3 gems per turn, so is 3x+ better than a clam, which people generally agree make for overpowering stategies. Yet a hammer is so easy to obtain, single path of 2.

10% reduction in forge cost is probably a lot more reasonable. It can gain a 2x bonus against constructs as a thematic compensation
