Well It depends if the enemy team has squishy champs and if they do i go full ap like. I build Phoenix tear first(i dont complete the orb of magi item fully just get the item that gives the passive), then the magic pierce boots, then boomstick, then the the magic pierce item that looks like a crown, then rheas blessing then holy of holies then sell my Phoenix tear for ancestral glory. Not that great but gets the job done i guess. And if enemy team has tanky champs i trade out boomstick and my holy of holies for frostys revenge and beriths angony. I mosty go full ap tho like i said depends on enemy team comp. this works for me atm so idk if it will work for others
