Both runs could be better. Durin had poor timing switching back to Noelle (missed the burst extension) and mavuika was kinda messy and they could both be significantly faster, by like 4 seconds or something. But they're incredibly close either way. Durin does more DPS, and Mavuika is kinda a mix of durin's light and dark mode. More damage than light mode and less than dark, but buffs Noelle's damage about the same amount as Durin's light mode. Overall, c2 Mavuika is a little better than c1 Durin as a subdps - she is comfier to use cuz she doesn't need energy, has longer uptime and generates more particles. But well, Durin has one less constellation and a much worse artifact set (noblesse vs Golden troupe) - although i think his weapon is a bit better - Myst splitter vs Wolf's Gravestone. Also... he frees up mavuika to be on her own party as a DPS. Long story short: Durin is awesome and best nod krai char so far by a long shot. (sorry ineffa)
