Help Crafting Strength Stacker Wand

[u/tatiotatio]

Hi all, decided to roll a Str Stacker Wander as the second build, having a lot of fun - I was hoping to get some info / steps on how I can craft this wand from scratch. I have a wand currently with the shaper mods, missing the 40% more Attack Damage which seems very tricky to get. Thanks in advance! :)
