Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Runes with no cdr
Runes with 10% @18
I prefer the runes with mr because Kha'Zix is VERY vulnerable without his jump(E). When you get cought out with Kha'Zix with no E i like that magic resist to keep me a bit safer were that cdr woukdnt change anything.
Evole Q first then E and last you can evolve W for 3 spikes and some extra damage or R for longer stelth and 3 uses insted of 2.
