Here's a shitty Night vs Snow build damage test on the second boss rush stage.
Comp is 70 Shia(T1)/40 Tilia/40 Jinglin(T1), main skills 4/4/4. Discs are 70 Summer Welfare/70 Minova/40 4* Light one with Misty on the cover.
Worth noting that almost all of the Snow damage is on boss while Night pads it with boss add damage(Snow struggles with killing them though).
