Context: Welkin player, invests horizontally (more characters, less dps). All of these are C0R0 except Furina. I am able to clear end game content, and Fearless in Stygian but it takes time and effort.

I was hoping getting their BiS would make my experience easier. Their cons look very tempting as well. Im not sure if investing vertically at this point in time would be smart, never tried it.


What would you choose? And for those who invested vertically, was it worth it? Thanks!
Which would you choose? R1 for Mav Skirk Nefer, or a new DPS C2R1?
