Such a long video just to say "have good artifacts".
Well it was more or less which "sets" to use, but yea, that's 98% of the endgame in Genshin, have good artifacts. I feel like the break even point with the Dragonspine spear is when you have over 150% crit damage though. Without it, the Crescent Pike just does too much supplemental damage. 30k ice drops sure are nice though. I also don't like how Bennett is included in the group because if I don't want to use him, my numbers are going to be down about 15% across the board, but whatever.
I'm a long way off from Min/maxing Rosaria, just got my Childe mostly maxed out yesterday. I still haven't farmed any specific artifact sets, and everybody is using either gladiator or wanderer's sets with misc 4* or random pieces I got from the book rewards or drops from something, so I've been holding off on farming any artifact domains until I get all characters and weapons to 90 or talents to max (crowns not included obviously). I haven't even done a single fight in a dedicated artifact domain yet, lol. It takes way too fucking many materials to get from 80-90 for both weapons and characters. I get that it's just yet
another time gate that MHY put in the game, but it really punishes people that play like I do and want to build a lot of characters at once. At least I have one main DPS nearly done, and I'm not far behind on Jean and Ganyu too. That pretty much covers any multiplayer content I'd need to make a comp against.
