It is easy event. o.o normal auto It's enough.
To be sure, I left the autoskill in R team for quest. I'm lazy.
I run autoskill for snatch with double Vlad but didn't really see any improvement, usually 4 4 16 chests
Snatch and Vlad will increase the chance of getting 4 gold chests rather than 3 gold chests. With no buff you'll get 3 chests pretty frequently, while with high buffs you'll usually get 4. While it makes a difference, I usually prioritize leveling kamihime over optimizing drop rates, and I can't be bothered to constantly swap drop rate accessories in for new characters.
If you want to optimize farm rate, create a rainbow team using every drop rate accessory you have and use Vlad for the all-element elemental attack buff. If you want to Auto, you'll need some strong characters and good debuff coverage to clear Advent Ultimates on Auto. It'll help if you have enough accessories for your best element to weight the characters towards that element too.
