The new Dark Harvest was released recently, and with it has come a fair amount of feedback - some good, some bad. However, most people I've talked to can agree that the new Harvest is good, albeit a little harder to build around... Unless you're playing Warwick.

In case you don't already know, the new Dark Harvest's ability text reads: Damaging a champion below 50% of their maximum health by any mean deals 40 − 80 (based on level) (+ 5 per Soul) (+ 25% bonus AD) (+ 15% AP) bonus Attack damage (Ability power) (Adaptive damage) and reaps 1 Soul. This cannot happen again for 45 seconds, resetting to 1.5 seconds on champion Damage rating takedown.

What this means is that, in order to efficiently farm Harvest stacks, you need to monitor its reset counter (or don't, depending on if you're able to hit the 1.5-second cooldown) and make sure you're fighting champions with either 50% health or lower.

This is where Warwick steps in: His W (though in most cases it's more like a second passsive), Blood Hunt, lets you track down enemy champions with 50% or lower health, and gives you both a speed and damage increase against them in combat, as well as a movement speed increase when "hunting" them out of combat. This all also triples if they're below 25% health.

So, essentially... Blood Hunt gives you free Dark Harvest stacks, in a sense, since you don't even need to kill the champion to get the stack, and ganking a hunted champion resets the Harvest counter.

So... How do we play this synergistic war machine of a build? It's honestly not that complicated - you'll start out with Warwick's basic Jungler gear (or you can build aggressively if you want to take the risk of not leveling as quickly as your fellow laners), and build into a mixture of Trinity Force, Ravenous Hydra, Sterak's Gage, etc. depending on what your situation is and who you're playing against.

My recommended trail against physical damage champions is:
Basic Jungler Start, into
Tiamat, Vampiric Scepter and Pickaxe, into
Ravenous Hydra, Stalker's Blade (if possible, could always build Blade first as well), Stinger, Sheen, Phage, into
Trinity Force, Blade - Bloodrazer, Pickaxe, Ruby Crystal, Jaurim's Fist, into
Sterak's Gage
And the rest is up to you - defensive or offensive, the choice is yours.

My trail for magic damage champions is the same up until you build Ravenous Hydra - instead of building into Trinity Force, try to build into either Locket or Zz'rot as quickly as possible so you can better combat your opponents in the late game when they have much stronger items. From there, it's the same build, and the same adaptive choice once Gage is built.

This build is NOT FLAWLESS - I will say that now. You are still very prone to tanks and AP-built champions, as Warwick doesn't very efficiently build items that both help him along and combat those two types. However, if you're facing neither a tank or an AP'er, you should be alright.

I know at least one person is probably going to question the runes on this build - "Why Alacrity? Why not something else like Triumph?" And to that, I say - Warwick is an attack speed-based champion at heart. If building this correctly, you'll probably be getting a LOT of champion kills and assists, so free attack speed for each one really helps, especially in the late game. As for Alacrity, I think that one's a no-brainer: It just adds to the buffs Blood Hunt gives you against low-health champions.

As for Harvest's sub-runes, and the stat runes, feel free to change any of those apart from Ravenous Hunter to your liking. I've found that a combination of Cheap Shot, Eyeball Collection, and Ravenous Hunter work well, though you can swap those out if you feel you have something that would work better.

That's all I've got for now. I'll probably continue to edit this build as the preseason continues and the game's meta shifts, but in the meantime, good luck, have fun, and happy hunting.
