Catalysts & Beastiary 30% Corruption

If I have a ring with maxed out catalysts giving me 20% to resistances, if I corrupt it to 30% quality with the beastiary will it boost the resistance bonuses from the catalysts or do I lose them?

Bestiary recipe only works with Weapons, Shields and Armours. Same goes for Perfect Fossiles.
Catalysts, on the other hands, work only on jewellery. There is actually no way to make a Catalyst quality raise over 20%

Nevertheless, if one day a certain currency or method comes to exist that will be able to raise even quality from jewellery, then it would work as you suppose.

Ah thank you, it let me add the ring to the crafting window so was concerned.

Crafting Benches, all around the game (even safehouse workbenches), can hold (and will hold even if you DC/logoff/etc) any item you put in there, no matter if it actually have sense to even do this.
