Shiv-PFW

close quarters & high velo mag really good damage amp
swift stiker enables you to take out enemies faster
fire rate really feels better with this

you want to take spirnt boots and extra stamina for this build, as shiv you will be running around the map alot
this will enable you better
i take healing rite if my lane is hard( enemy is super agressive) it is better than going back to base and regen
enduring spirit for lifesteal, you can skip and focus on vitality mid game items w/ better lifesteal

extra spirit for damage
improved cooldown for 2nd skill, supressor for slow later
als ogood sicne you fight upclose
quicksilver, so you wont waste time reloading while fighting up close.

with quicksilver reload, these items make you kill enemies alot faster, warpt stone no really necesarry
focus on spirt and vitality items

iteams you really want are spirit lifesteal, healing booster and divine barrier
other items depend of the enemy type you have
if they have slows or debuff, go for debuff reducer and reactive barrier
sell healing rite and enduring spirit to make space
other items go to flex slot

upgrade spirit items
more amage, slow and cd for 2nd skill

main items to take are unstoppable and curse or phantom strike
during late game you want to target their damage dealers(haze, vindicta etc..) unstoppable makes you immune to spells so you can focus them, curse silnce them and phantom strike blinks you to your target and also disarms them
goal for this build is to quickly kill enmy during unstoppable duration
