Core Items.
This build relies primarily upon Alpha’s base damage through the early game. Start with Swift Shooter for your Jungle clear, then invest heavily in defense. Work towards a Sorrowblade, then round out your build with a Breaking Point (or Bonesaw, sometimes both) to allow Alpha to continually ramp up as the fight pulls onwards.
As Needed..
War Treads provide decent HP to keep Alpha in the fight, while the active allows her to bring the whole team crashing down upon her targets. Aegis and Atlas Pauldron are great for extending the time before Alpha needs to use her passive. When in the lead and being aggressive, a Bonesaw or Tyrant’s Monocle are good options to push Alpha into maximum overdrive.
