Hello Summoners. This is a AD burst damage with some survivability guide. This guide requires some skills to use as it offer less survivability than other builds but pays off in the damage output. Here we go. (To those who are wondering why there is only 5 items, I have a section below for the last item.) Remember this build does not promise you anything, its just a tool to help you go down the right path with Yorick.

Pros
Fun to play.
Does massive damage using this build.
Has minions.
Build-in lifesteal.
Good harassing Skill.

Cons
Can be quite squishy.
Low mana pool.
Underpowered at the moment.
Looks kinda funky.

I take AP Marks for obvious reasons... For Glyphs I take cooldown reduction per level as it stacks on with Spirit Visage and Masteries adding to 22% cooldown reduction. Flat Health Quintessence and Health per level Seals for survivability, it also works well with Impaler if you are planning to get it as your last item.

Core buildThese are the three most important item of the build. Trinity Force's passive will work when you use any of your skills, and most importantly yourOmen of War. By the time you complete your Trinity Force, you should be able to knock on some serious damage ranging from 400~500 at level 13. The Bloodthirster is a very wonderful item, 100 damage and 25% lifesteal, it works like a charm with your Q and Trinity Force. Why Spirit Visage you might wonder... Well you're a noob for wondering why Yorick should get Spirit Visage. I kid you but no seriously... Spirit Visage offers 10% cooldown reduction, health, magic resist, and 15% extra healing power to yourOmen of Famine for only 1550 gold. WTFHLKAJSDLKASJD right? :D

The work of gravediggers is essential amongst the living, but invaluable in the Shadow Isles. There are many shades of death there, and each is embraced rather than feared or reviled. One can only ascend from one state to the next with the magical aid of a skilled professional. At the end of the first Rune War, Yorick Mori made his living as a gravedigger. His family owned and maintained the Final Rest Memorial, one of the oldest cemeteries in Valoran. The shovel he employed for his work had been passed down for generations. Each gravedigger taught his son that this shovel was imbued with the spirit of every forefather, and that those spirits would protect him during the long lonely nights amongst the tombstones. To his eternal regret, Yorick died without an heir, bringing the proud Mori line to a close. His body was interred with his shovel in the family mausoleum, and the Final Rest Memorial soon fell to ruin. Death, however, was not the end Yorick had expected.

Yorick emerged on the haunted shores of the Shadow Isles - not quite dead, definitely not alive - still clutching his beloved shovel. He soon learned that with it he could act as a ferryman for the Isles' undead denizens, helping them climb death's many-tiered ladder. This proved a curse, as a gravedigger must ''bury his quota'' before he too can ascend, or so the legend goes. No one knows what ''his quota'' is. Yorick dug tirelessly, waiting in vain for the day when he would be freed of his burden. As decades turned to centuries, the shame of his failures came to a head. He returned to Valoran to find his corpse, convinced that salvation might be buried with it. When he arrived, no trace remained of either the mausoleum or the memorial. Hope nearly lost, he discovered the League of Legends, and there saw an opportunity to immortalize the family name he allowed to be forgotten ages ago.

''Die first, then we'll talk.''
-Yorick
