Depending on situation if you need utility or dmg buy first headhunter or Sup stam After you bought either burst or Headhunter defently buy sup stam After that comes your survivability utility for teamfights
Sup cooldown and RR can be bought if cant cant safe up to a t4, generly SO is insane Sup Stam can be used on any of your abilities, if you need mobility...2nd if you need more burst dmg 1st, if you need more consitent dmg 3rd and if you plan to be a consistent playmaker on 4th
These items if properly timed well in their powerspikes can also be realy good for lash, veilwalker also regenerates the temporary shields which can get quite absurd very quickly
This build is mainly ment to be very cost efficient and uses lashes powerspikes very effectively. Granted if the game goes longer and you reach like 40+ Souls then you should start exchanging items for the big boy items. From my expierence though i never actualy made it to the end in my games, since the games are around 20 to 30 minutes.
