How can I defeat Eorforwine?

I am currently power 135 and Eorforwine is recommended 90. However when I try and battle her she easily defeats me.

I am using a heavy shield and axe setup, and trying to dodge her attacks and then hit her. However I am finding that she either blocks me with the shield and then hits me twice which takes away half my health.

If I try and use range and shoot her with arrows she throws poison bombs at me which I cannot dodge out of the way of because the radius is so big, and she throws three in quick succession.

Whilst I am trying to then close the distance she drinks a healing potion.

What techniques can I use to defeat this Order Zealot?
