Hello!
I'm making a modpack and some mods have items that are strong but have very low durability, the problem is that with this item you can make some items too strong, i was asking as the title says, an option to disable the Hardening Catalyst or make a blacklist where i could put specific items in, that way it can have more compatibility with some mods.

There is already a blacklist - simply put items you don't want the hardening catalyst to apply to into the things:hardening_catalyst_blacklist item tag. Additionally, if you want to disable it completely, you could just remove the catalyst's recipe - there is no other way to obtain it

Cheers
