Does Black Cat Need the BW Relic to Be Duped?

Riryoku

I recently opened a loyalty crystal and finally pulled Black Cat! Now, I need to decide which relic to use: a 6* BW relic that's not duped or a duped 5* one. So, my question to fellow Black Cat players is: does the relic's dupe provide a significant benefit? I'd like to focus on ranking up the best option.

Not really. It just adds some more attack, and personal cruelties. You still get your bulk of utility and damage from the relic, and you crit a lot when you fail abilities so I’d say no. But it is a nice bonus to have.
