My Emma is level 62, +20 Gears, 4-5* uru, CTPD (160 proc), and Stage 9 Hawk's Eye, mythic uni.
I'm 95% sure she can clear level 40 Maw, but I haven't actually tested it yet. Her new uni really boosts dps. She blew right through level 35 Maw, and she struggled with that before the uni.
She seems to be right on par with my Jean (5-6* uru, stage 12 Hawk's Eye, Fire DMG/Ig Def/140 proc).
I'm running 41 with Jean, so that's not too shabby.
