This is a very good guide but very blue dependent. Getting some more mana regn early wouldn't hurt. Also ryze and veigar arn't the easist prey for cassy (knowing i play both). Would be nice to see a bigger list of champs that she is good against and bad against. All in all a good guide. (If you need any help with it message me)

I agree on Runes, Masteries, and Skill Order

Yo!

Thanks for the fast response, I am awara that my grammar is far from perfect, but I'm working on it.

I thought through the runes I had, and played a few matches with AP/lvl runes and they DO seem better than the old ones.

A Couple things with this guide:

- lots of grammatical errors, needs at least some clean-up
- MPen Glyphs are meh, unless you're hellbent on dominating early game (which you already should be) I'd get scaling AP glyphs (ap/level).
-Spec: with the recent mastery changes I really advocate for this spec, Good job, especially because Cassiopeia doesn't have great burst at early levels, He ability to finish champions off is very limited, the Executioner mastery is very good on her.
- Rod of Ages is built very late, almost makes it not even worth. You'd probably be better off building a Banshee's Veil instead.

+1 for generally good info
