18/10/18 with this guide. If you're going for more of a tanky aspect, you should add Zhonya's Hourglass or Abyssal Mask. I swapped out my Doran's for one of the latter, and it elped a lot.

I like the idea. Veigar naturally has a lot of AP, so building some more defensive items is a nice twist that's not often seen.

However, the guide could use some work. If you hover your cursor over "Builds & Guides" above, you'll see "Getting Started Guide". That'll teach you about how to make your guide a lot more attractive - colors, columns, things like Rabadon's Deathcap vs. Rabadon's Deathcap, etc.

Another thing - why flat mana runes rather than mana regen? His passive works well with things like mana regen seals.
