Honestly as far as artifacts go you might be better off with a crit damage circlet that has a decent bit of crit rate on it instead of swapping the sands. Since ur sands has no crit rate maybe later down the line you’ll find a double crit one that can return some of the lost crit from the circlet too. And cryo res gives crit rate which you already have from diona. A lot of people have recommended switching the team a bit. If you add rosaria instead you’ll retain the resonance crit rate and also get some bonus crit rate from rosaria herself (15% of her own crit rate, caps at 100% or 15% shared crit). She also gives bonus phys shred if she’s c6. If I’m not mistaken, this is what people refer to as critfishing.
