Jane is surprisingly fun to play! Shiyu 17 - Impact Seth + Anomaly Lucy = Caesar + Burnice ?
I was gonna skip Jane to go for Caesar, but her gameplay and characters are amazing! Seth's Defensive Assist can help Jane get 1 Quick Assist and Shield with 100 Anomaly Proficiency, but Jane can only regen Passion with Perfect Dodge or Defensive Assist.
4 Swing Jazz improve 15% damage when Enemies are Stunned. Jane will do 3 Assault with 1 Ult and 2 EX each Boss Stun, 4 Swing Jazz matter for her.
Seth is compatible with 4 Swing Jazz as his 2nd Core Skill - reduce Anomaly RES by 20% - is also trigger by his Chain Attack, 2 Hormone Punk. This skill isn't that useful, 3 Assault with 20% is still 3 Assault. My Jane had 9 Assault during the whole Shiyu 17, adding 1 more won't matter much, Seth need to be well built + the fight must be long for this to matter.
Standard Seth should have 4 Swing Jazz 2 Hormone Punk with ER Atk Atk. Some use Lycaon / Koleda Stun weapon with Impact and 2 Shockstar, I think that's the right approach, 20% more Impact won't matter, but 50% more Impact matter.
I like my Ben on 4 Infernal as Ben could have very high personal attack and his Shield boosts 12% Crit Rate. I prefer ER on Ben, as my 2 Piece are Pen from the same Domains, too low ER isn't comfortable. If damage is preferred, I'll give my Lycaon Corin team 4 Swing Jazz Lucy, Lucy is as strong as M0 Rina for them - I tested using the event.
Jane could be supported by another Physical using 4 Freedom Blue that have enough Energy for EX. Caesar Impact will probably be this character, Jane will also need Burnice for this team to work. It seem that Seth will be shadowed by Caesar Burnice so bad in 2 months!
