I could see type weapons being made this way , the sunset quest line and hearts of ID can be a long process especially getting id that have done it to tag along, to speed it up. Possible swap in for type/me type/sh etc
Then use bone badges to add specials to types separated in 3 tiers , tier 1 buy with gold tier 2 buy with silver and tier 3 bronze.
As to not make it easy a Claires deal hand in , So to make your type saber with stats of desired 9* , you will need to hand in a pallasch of each element thunder blizzard Hell etc . then once that completed your 9* desired stat exchange can happen.
