I'm making Laezel a polearm build but at level 4 take a +1 str feat to get 18 str (the one with triple jump distance).
I have to wait until level 8 to get the second attack option.
It works nice with EK because she can throw any bound spear and it returns. None throwing weapon like greatswords just do 1 damage when thrown

You add the ring and another item I can't remember that add an extra 1d4 thrown damage on top, and lob that watchers pike all day.
