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.
Cleanse: Why this instead exhaust? Playing as Trynda teach you that all exhausts and CCs are going to you, so cleanse all out is good thing.
Flash: Combined with Spinning Slash gives you a good tactic to get a kill or save yourself.
/all LOLOL TRYNDA HITS ME FOR 1600!11 WTFF!1
You will read something as this with this runes, 296%crit dmg + 36% (Bloodlust) is really amazing.
I dont have choose any boots because you get +30%mov with both Panthom (you can combine it with Spinning Slash + Mocking Shout with fleeing enemies), but before buying them you must buy something like Berserker Graves.
So that was my first build, and excuse my bad english, but im from Spain and I do what I can ;P
