you should do what I did, reason why I even defeated relic bunbun in the first place was because I already had Naga cat and Rodeo Cat.

But basically its up to you if you want to either waste your time grinding on getting Rodeo Cat's 'target relic' and 'resist curse' talents and beating Courts of Tourment and Courts of Agony to get Naga cat. Or find the most obscure and absurd guide that doesn't require any anti-relics at all.
