My Yoric can solo top.All of that items can help you whit ad or good ap.You can beast The guys get feed.You can spawm every 5 sec 2 gouls.Omen of famine and omen of war.

marke runes is dmg cause for the start you need to some good dmg if you want the first blood :).
Seal rune is for take less dmg at the start vs AD .Glyph why i take magic resis per lvl cause if you are vs a AP he can do a littel less dmg.The last rune is for vs tank you can do more dmg but not more to kill him.

This masteries is for spawm gouls fast and get some cooldown and 1 gold every 10 sec and it good if you solo top whit him cause you get more fast exp and lvl so you can get you skill more fast and get some kill easy.Also you need some mana and some mana regen at the start cause yoric gouls cost too much mana at the start.

i let you see if your ennemis get more ad or ap (it for boots choice you take ninja sabi or mercurie boots at your choice.Malamute is good for mana regen and for mana.Also is good for dmg.
Frozen heart is important to get whit yoric cause the ennemis ad will be slow.Nature force is good for heal regen and magic resis. vs AP. and the trinity force is good all ennemis.

I take flash and ingnite cause flash you can escape a gank or if you low life and ignite is for kill the ennemis when you down him at 120 heal or less or if he run whit low life.you can chose if you want ghost or exause .
