i dont know how to gear for skorns, and you build is different than the typical ww or ww/hota. that said, i would replace the helm for a 200+str 9 ias prefered mempo. the boots with IK boots if you need move speed, ice climbers with 150 ish str and vit no move speed if you dont (you have 24% between the lacunis and ice climbers, but irf u intend to drop one ull need it else where). ice climbers should be 100+ vit no str. on a good day you can pick up a 100-120vit pair for 3-6m, normally theyre about 10m tho. shoulders should be crafted VIT based. you want 200 vit/200str/ 50-60+ allres, armor and life % are a bonus, but it should have those 3 at the least. gloves should probly have 8 ias+ and 8-9+ cc, they dont have to be IK. you should probly have str/ avg dmg/ cc/ ias in ur non unity ring. necklace is useually prefered to have CC/CD/str/avg dmg. you cna pick up some vit on the belt, 230str/50vit is roughly 10m. would help life sustain if your skorn had life steal on it.
and remember these are just general things, skorns may need to be geared differently, but thats a list of things i would change.
as for build, i would reccomend bash(instigation)/frenzy, whirlwind(hurricane) in right click, wotb, sprint(run like the wind), battle rage(the fury gen on crits rune), and overpower(killing spree).
passives as weapon master, bloodthirst (untill you get a lifesteal weapon), and ruthless.
that builds for whirlwind build, use what you prefer tho.
