Mid laner builds 1st page TRIFORCE MID used to champions like adc witch are extra squizy or to champions have range spells and are really hard to kill them in team fight you can build the statik and go for full trinity force and then for infinity or you can build statikk then the phage from trinity and build infinity then or the most recomendable to build the statikk then buy from infinite the cloak of agility for 100% of crit.strike and then build trinity and then infinity (you can change statik with phantom if you make split push and leave the lane for ganks but the statik is recomended for 1v1 to your lane)not really good against Tanks.....
