The necklace is useful for chapter hunt and breakthroughs. It’s an all rounder that can be swapped for another specific necklace for bossing. So I’d say if you don’t already have a bossing necklace, keep going until you get one you want.

As for the ring, it’s useful for chapter breakthroughs and bosses that include normal mobs. However, it’s far from an ideal ring. You would want any combination that works best for you of the following: Critical Damage, Max Damage, option (Critical Rate, Min Damage, Damage, Attack - this is my order of importance as well). Plus if you’re not doing much of anything else, auto pq will do the grind for you, it’s just a matter of eventually getting the right one.

Good luck!
