I thought about how they could fix it where people would do dungeons.

Do what they did with the artifact weapons in FFXI byne bills and such, going through dungeons and make them rare to drop to make a good weapon that has its own weapon skill and have each dungeon drop different things for the weapons.

Have maybe a chance special boss monster appear that has a piece for the weapon in dungeon but pops rarely maybe doing it a couple of times till it pops, make the items to be sold on market.

Fates can be involved also you have to beat different fates in order to finish weapon and so many fates need to be done. need something like this make dungeons have random gear or gold bronze or tin in treasure chest or said artifact weapon items.
