League of Legends - Five Useful Yorick Tips by Zaaptastic

I will give a brief introduction to the intricate nuances and minute complexities that are involved in playing Yorick optimally.

1. If the other guy walks near you drop a ghoul on him. Repeat for 10-15 minutes. We Yorick mains call this a "laning phase".
   
2. If you're taking damage and you have no idea why just drop ghouls everywhere. It makes you tanky for some strange reason.
   
3. If your team is complaining about you being a "useless champion" just creep block them by dropping ghouls on them (it doesn't actually work but you let your teammates feel your wrath through the mighty power of ghoul).
   
4. If you don't know how to itemize just build whatever the fuck you want. Anything you could possibly have gotten from the store will at least do something interesting. Then drop a ghoul on the shopkeeper to let him know you mean business. Make sure to do this outside of fountain so you don't get the mana regen. This makes for maximum intimidation.
   
5. If your ADC is getting dived, ult him then drop ghouls on whoever is diving. This way even if his feeding ass gets killed at least he can pick up that free CS afterwards. Also this makes you tankier for whatever reason.

Bonus tip: If you look a bit above your character's model, you notice a strange rectangle shape that is shaded partially either green or gold. If you notice this colored region become too small for your liking, just drop ghouls everywhere. One of them will end up being that one that heals you, and you'll be good to go before you know it.
