This baffles me

FortressDef3 + Renewal

Darting blow with the +4 stats should still let her double a lot, if you have people with hone speeds and attacks it would help a lot, then green tomebreaker, other than that use the skills she comes with, you get 24 sp per kill so you can always change darting blow when it's over

-Att isn't too bad compared to -Spd due to the sheer power of Moonbow + Wo Dao+ type weapon. Sonya will struggle to defeat opposing mages in one round without the attack boost, but she'll still be functional

Got random 5star Hero on second full draw.... Klein...... -atk + def...... game hate me......... reallly hate me........
