Blacksmith Skill to upgrade gear

Not a fan of weapon maintenance but weapon upgrades with a risk of breaking it when you upgrade would be a great way to maintain demand for resources: - you introduce a blacksmith skill and a blacksmith bench for upgrades - you introduce 3-5 weapon tiers for the same weapon -- level 1: base weapon with base stats -- level 2: increased stats + different aura + you need two lvl1 weapons to craft it and there is a 50% chance for both weapons to break (you lose both) -- level 3: increased stats + different aura + you need two lvl2 weapons and there is a 50% chance for both weapons ot break (you lose both) -- and so on... To craft it, on top of using the 2 weapons with the % risk of breaking them, it can consume some rare resources like the new stuff dropping on S7+ in the Everdune (soulstone, essence of whatever, etc.) and a significant amount of Gold. As the Blacksmith skill level increases, the chance for both weapon to break reduces (you need to cap this to keep a relatively high break chance to make those weapons truly hard to obtain). You can even stagger the introduction of higher tier weapons as each tier introduction will boost demand for the resources needed to craft it. For example with the introduction of every new dungeon, you increase the available tier by 1. I think this is a good way to maintain demand for existing resources without disrupting the existing mechanisms but building on top of it instead.
