Predecessor Builds > Feng Mao > Feng supremacy

Major bully build for feng with unlimited skill usage (no having to go back or steal river buff).
Situational items, coming against lifesteals or regens tainted blade when necessary. Perforator gor an overly tanky team. If you're demolishing and want to go crit, stick them on in place of the armour items towards end game, if the opposition hasn't already surrendered.
Master Feng and most games decent K/D
