Good descriptions and everything, but I am more of a visual, put some pictures or something that I can look at. I wont vote down at all but there are a few things to fix. your clear on most of it. if you just went in depth on what items to get in which lane or possibly enemy champs that are hard to lane against. what abilities go well against what champs. small things

Well I must agree with SwiftHikari1764, but on the other hand the guide is pretty nice... One more thing: Why dont you trz Nashor's Tooth? It's pretty controvertial as I've never seen this item on any other AP carry, but consider the cooldown, ability power and mp5!!! Also a bonus attack speed is not a waste even if you autoattack only a shortwhile... I get Nashor's instead of Zhonya's!
All in all a pretty good guide and you get my vote!!!

As Morg as my original and current main, I want to point out some things here. Not cutting you down, just something to consider in this build and for actual in-game play.

Firstly, Masteries. Shame shame shame for using Greed. #1 useless mastery since it generates 6 gold every minute, or 30 gold every 5 minutes. With her W, she masses that and more on creeps alone. Better off in Good Hands.

Next, skills. This is more personal, but Morg can be a great pusher if you stack Dark Binding instead of Black Shield. It's sketchy because you don't have the line of defense to rely on, but if you have bad map awareness or are rushing in, it's useless to you anyway. W+Q traps them on Soil, so you get maximum damage output for your level, and are more likely to earn early kills.
Purely a personal thought.

Third is items. Again, a little more personal, but two Doran's are unnecessary.
Doran's Ring -> Sorcerer's Shoes -> Frozen Heart -> Blasting Wand to stack either Void Staff or Rod of Ages, followed by the item not purchased, Rabadon's Deathcap, and always always always if possible an Elixir of Brilliance.
SS for the movement speed required early on, FH for the CDR and reduced AS + adding to your mana pool, Void Staff and Rod of Ages for obvious AP stacking reasons, Rabadon last only because it takes the longest, and while the 140+30% is nice, it's better stacked last so you can come out blasting as a tank support. At that point, you can 1v3 easy.
I also say Elixirs because of the CDR and AP boost. No reason not to have it.

Summoner skills I won't get into because that's also a personal preference to how one wants to play Morg, what they're anticipating they'll do before the game starts. But I'd carry Heal/Clarity just to stay in the lane/fight longer, as you claim. Exhaust maybe to pin down that pesky champ that wants to escape, or ignite. But Clarity keeps you in your lane early game to level faster, and Heal keeps you in the fight late game against fairly good enemeies who want your blood.

Hope this helps n.n sorry it's long. Just passionate.

You should add a situational items paragraph explaining, for example, get void staff if they're stacking mr or stuff like that. Just a suggestion!

I love this guide it made me get a penta with morgana! +1

Great guide! +1 from me
