just a demonstration at this moment..

Can you post some passive tree of it ? (use poedb https://poe2db.tw/us/passive-skill-tree/ ) and/or if needed the atlas passivetree (same site) ).
And a short video exposing the items you are currently using ?

I'm currently leveling one (early A4) but kinda of strugling (nice def but weak offensive)

Kind regards

edit : You deleted the video, dunno why, I found it really good.
