Nice build, but I prefer Shurelya's Reverie instead of Eleisa's Miracle. :)

I was talking about spending extra gold on elixirs after you have a completed build.

As for Sheen - It's a solid item for sure. I guess if you're able to use a lot of Qs on the enemies, it can be well worth getting. On the other hand, if you aren't able to rely on your autoattack against them, it's a complete waste of an item. I guess the biggest problem is that Yorick doesn't have any dives, so you might not be able to ever really melee them unless they let you. I'm more used to a tanky caster Yorick, just throwing minions everywhere, poking the opponent to death, and forcing them to recall, on which a Shurelya's is more reliable.

Yorick that frickin beast..

"Each time you go back to your base and can afford to, you should sell your boots, buy all the elixirs, and then rebuy your boots." why???
you can buy elexirs with a full build x)

Havent played him alot, but why have you chosen not too use Sheen earlygame? isnt sheen (later Trinity Force) very strong item on Yorick?

Thanks for the comment. I added a little more about why I get Shurelya's. Also, added an after-build section where I went on about possibly selling the Shurelya's, since it isn't as strong late game.

shurelia should be replaced =/
