Ruby gear is more powerful than diamond gear, but rubies are fairly common. I'm loving this mod, but rubies would be game-breaking on my server if the spawn rate says the same.

Describe the solution you'd like
I want to be able to configure the spawn rate of ore so I can keep rubies in the game but make them much rarer.

Describe alternatives you've considered
I could just switch off rubies in the config, but I want to keep them, just at a lower rarity. I haven't seen a way to change the spawn rate in the config.

I think the real fix for ruby tools is to make them less powerful. However I do also want to redo the ore configs to be fully customisable.

That also would be okay with me, especially with netherite on the way. Do you have any idea when that might be implemented?

Will there be a ruby gear nerf also? Someone in the discord said reducing ruby ores could mess up chrome in the endgame.
