It's really no surprise that onyxes and the items crafted from them have become kind of worthless over time. I've talked about this before; we simply have too many sources for onyxes. In order to not turn furies and stones into unsellable items those should be cut back and perhaps a sink should also be implemented.
Shooting star
The first source I want to talk about is shooting star. Every star there is guaranteed to be one onyx entering the game. The we get 8-12 star spawns per day per world. I'd say most of those are mined, to pick a number I'd say at least 10 stars are mined every day. That would mean in a good week or two we could supply everyone online with a fury and stone. Cutting the amount of stars spawned comes to mind, but given that that would make getting the outfit (which is already kind of not worth getting at all) take even longer that isn't something I'd want.
We could have the onyx be a chance to obtain and get some kind of drop table that would be given to one person every star. This droptable could contain a few different amounts of stardust, mining exp lamps and the onyx. That would already cut down the amount of onyxes from stars by a massive amount.
Tokkul shop
Every jad run gives you enough tokkul to buy two onyxes. Shenven assigns jad nowadays so it does get done a little bit more often than it used to. Simply doubling the tokkul price of onyxes would be fine. It might suck for the coming months after the change but should ultimately result in a similar or better reward in terms of price.
Onyx drops
We used to have more monsters dropping onyxes but that number was cut down (thanks mary), I believe we could still take that further. I think it can be removed from KQ, KBD and Chronozon's droptables. Thematically it would make sense for obsidian dragons to drop them, so I wouldn't mind keeping it on them. I think it could be removed from them too however.
Regen bracelet
This could've been a good sink for onyxes, so I'm suggesting it's turned into one. First off, 2% is kind of meager, buffing it to 5% would make it seem a lot more impactful. I'm suggesting we make the bracelet repairable with onyx items (except bolts/tips). 25 or 20% of the charges restored per onyx item would be enough.
Rings of stone could also be used to recharge imbued rings if we want another sink specifically for them.
