Help with power build

I know that staff is the best option for power Weaver, but what about dagger or scepter? Are they viable? Played most of the time backline with Tempest, wanted to try something different this time.

Used berserker with Fire and Air in HoT for pve, can i do the same here?

Just to double check: This is only for open-world PvE, yes?

If so, then I would say Power Dagger/x can be pretty effective, though I have doubts about the Weaver's dual skills. If you really want to get in close, Sword/x can work; though be careful with your interest squishy-ness.
