Gemling SSF build ideas?

Completely overwhelmed by the options of builds here tbh. I want to use the cast on dodge + boots stuff for some really nice mobility, then ideally with a button I can press to oneshot screens in between dodging about with minimal aiming. Not manual grenades though.

Siege ballista nades seems like a good option if its easy enough to get online? Could explosive shot + reload on dodge work?

Or a full on cast on dodge caster setup for dmg but not sure how viable that would be in SSF, ie is it possible to make ember fusillade actually clear without gloom shrine?

If anyone has any experience with these kinds of builds some advice would be appreciated lol.
