where melee riven mod is, replace that with [Fragor] croniton and thats my build this is a decent speed and life steal build with good damage oh and i know with the actual build i have only 40% critical chance its fine as soon as you hammer someone or a few and you speed up there you know u hit a critical and with the rapid hits u'll have a good chance to hit those and with every combo multiplier you know what [Blood Rush] does it'll take care of the missing critical chance increase.
