>>538418468 I'll give a quick list starting from cheapest to expensive

>Damage items
Close quarters, headshot booster, restorative shot, opening rounds are all good early lane options. Mid game you'll want kinetic dash and or hunters aura. Be sure to upgrade the previous item as headshot booster goes into headhunter and close quarters to point blank. For late damage items frenzy is good and some players swear by weighted shot but I don't really like it.
>healing items
Early game extra regen, extra stam, sprint boots reactive barrier, battle vest

Mid game enduring speed, debuff reducer/debuff remover and fortitude.

late game juggernaut, plated armor, spell breaker

>Spirit items
I'm not gonna lie I don't really get many of these items and the ones I do are melee items which I exuded in the other categories because It seems like you don't wanna mess with the melee system. I still think melee is useful its just something you don't spam like a ape.
So uhhh cold front and like radiant regen. upgrade to artic blast late game. Honestly experiment in this department if you really don't wanna do any melee and figure out what you can do.
