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.
As soon as you get your Madred's Razor you should use Ruthless Predator ~~~~WITH 50 FURY~~~~ as often as possible on high-health targets Each hits has a chance to proc it, and if you're lucky you can deal an additional 1500 damage in a single skill.
This also makes dragon a piece of cake when you get your Vampiric Scepter.
The dodge items are there to grant you extra safety, and also help you in early/late game when damage dealt to you can easily kill you.
Your Ruthless Predator should be used in the following combo:
-Open with Slice
-Use Cull of the Meek
-Go back through the target with Dice
-Now you should have 50++++ Fury and 3 stacks of Black Cleaver active.
-Now use your Ruthless Predator to deal insane amounts of damage.
The reason it deals such considerable high damage is:
-Proccing Black Cleaver
-Benefitting greatly from Armor Penetration
-Proccing Madred's Bloodrazor (basically with 50+ Fury you deal additional 12% total health damage)
-Proccing from Trinity Force, if you're lucky, you get two procs.
-Possibly can crit as well (not sure if it can, but Gangplank and Nasus' abilities can, so why can't ours?)
-Also works with Lifesteal! (hence the Bloodthirster)
Why not getting 15% CDR boots?
You need the survival.
You will be blue buffed all the time with your jungling speed
You are quite slow, so dodging and then increasing movement speed is a great way to get away.
In the end you get a quite tanky solid melee damage dealer, who can shut down carries nearly instantly with the combo i described.
And if they survive. Just do it again. It's that simple.
If you're not so sure about getting a Bloodthirster (dying alot), try getting a Wriggle's Lantern instead. It also helps out your team, because you can ward freely. Then replace your Madred's with a Frozen Mallet.
Armor reduction CAN and WILL go into the negatives and thus GREATLY increase your damage by the percentage described. So a -14% armor will increase your physical damage against them by +14%.
