Introduction
Hey Everybody!
I'm TonsOfFun and this is actually my first guide, so bear with me. I recently bought
Yorick, the GraveDigger, and have had success in destroying the competition with my ghouls. I hope you enjoy the guide and give my build a shot! :)
Skills

Your passive. Each one of your abilities (even
Omen of Death) summons a ghoul. Through your passive, each ghoul reduces the damage you take by 5% and increase the damage of your basic attacks by 5%. So having all ghouls up at once gives you 15%-20% reduced damage taken and 15%-20% extra damage on your basic attacks. Each ghoul has 35% of your health and attack damage. So having the 3 ghouls from your basic abilities summoned, it is like you have a second
Yorick with the 105% damage.

This is your main damage tool, but the only ability that requires you to be in melee range. I take it at level 3. 7, 8, 9, and 10 in order to deal the maximum amount of damage.

Your slowing tool. Take this at level 2, but max it last. This ability will do the least amount of damage, but is important for chasing and escaping.

This is your 2nd damage tool and sustain. Take this at level 1, 4, 5, 12, and 13 for early game harassment and sustain.

Your ultimate. Max out when you can at 6, 11, and 16.
Combos
Harassment:
Yorick is very capable of getting first blood in top-lane. Use
Omen of Pestilence to slow the enemy and then
Omen of Famine to harass from afar. Throw in a a basic attack or two if you are close enough.
Max Damage:
In order to ensure the maximum amount of damage and the use of all three of your abilities, open with
Omen of Pestilence, then
Omen of Famine, and follow up with
Omen of War for "TONS OF DAMAGE"!
Ultimate:
This combo is the same as the "Max Damage" combo, but the difference is activating
Omen of Death in order to deal more damage through the summoned revenant. Through your ultimate, if you die you will be resurrected for 10 seconds in order to secure kills, change the tide of a team-fight, and enact vengeance!
Exhaust and Flash:
Use
Exhaust when you need the extra slow or the damage reduction on the enemy. If you combo
Exhaust with
Omen of Famine, you can go from very low health and losing to half health and winning.
Use
Flash when you need to flash over a wall or just away for an escape.
Flash can be used offensively to ensure a kill.
Gameplay
Early Game:
Focus on harassing the enemy champion and farming up minions with last hits. Try to force a fast kill, because
Yorick is very powerful early game.
Mid Game:
Focus on killing the enemy champion, ganking other lanes, farming, and pushing the lane turret as fast as possible.
Late Game:
Team-Fight Phase. You should be a more-tanky champion than most of your team, so you have the ability to initiate with
Omen of Pestilence and take a serious amount of damage during the team-fight while nuking enemy champions. Win the team-fights and destroy the enemy nexus!!!
Summary
Please try my build before bashing it's composition. I know the layout is very basic, but I feel like I addressed the factors that must be known by
Yorick players. This is my first guide, so sorry for the "basic-ness"... Please leave positive feedback and ways I can improve in the comment area! Thank you! And good luck on the Fields of Justice!
