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.
this is one way to play warwick. i still need to test it, but this was just something i came up with on the spot, and thought i would share my idea. the armpen is good for obvious reasons, the blackcleaver stacks with ww's ult, and wits end means that they will be low on mana at the end, and that means low on options. your AS is also very high, so your passive gets good use, you get good use from the bloodrazor, and also from frozen mallet because of the slow. anyways, HF and GL playing Warwick.
