Witch attack speed build, help!

Hello exiles!

So far I am loving Poe 2 with a buddy. I am a witch (summoner lvl 21) and playing with my friend warrior. I have recently acquired a legendary one hand *trenchtimbre* this passes my minions attack speed boosts onto me. I have no idea how to utilize this into a build. Google and forum searches have turned up empty. Any one have advice on how to utilize this?

Thank you very much for taking time to help!
