Need advice for planning tree - Dual Dagger melee Trickster (elemental/frenzy setup).

Hello. I'm planning out my next character for dual dagger attack style. Going going for elemental damage. Not sure which element (perhaps multiple). And Frenzy seems to be pretty good. I have no equipment or idea. So I'm starting with planning out my tree.

I was thinking Elemental Hit + Trinity, Inspiration, Element Damage, Multistrike.

Thanks!
