I choose to solo top Morgana for the creep kills (I get around 150 creep kills a match) and for lots of XP (I am usually higher/the same level as Mid Lane by the time mid game comes).

Why 9-0-21 you ask? Well Lets talk about the Offensive first. I take summoner's wraith for my summoner spell "ignite". The other 8 points are there so she can have magic pen. Now for Utility: GET MANA REGEN!!!! Morgana is a mana waster!!! Improve recall: your going to be solo top this lets you go back faster so you can get back to your lane faster!!! Transmutation: Even though her passive gives her spell vamp when you get this she gets MORE which means u can hold a lane longer!!! When your low on health but not mana you can cast your "w" and steal TONS of health back from minions in your lane!!! Awareness: HELLO YOU WANT TONS OF XP SO YOU CAN OWN YOUR LANE! Intelligence: Morgana has HIGH cooldowns so this helps with it some. Mastermind: reduced Cooldown for teleport and ignite!!

I'm going to keep this nice and simple. Mark of Insight: Magic Pen if they are building Magic Resist. Seals of Replenishment: HELLO MANA WASTER! Why do I choose these instead of Seal of Clarity? Well 1: they are cheaper 2: You can get your mana back faster at level 1 with replenishment instead of clarity. 3: You don't need anymore mana regen when you hit higher levels because of Tear of Goddess/Archangels. Glyph of Force: Hello Morgana is AP!
Quint of Potency: This along with your Glyphs give you a nice amount of AP at the start of the match.

Why I take ignite: If someone is trying to run and they are almost dead you can use ignite to finish them off. Also if they have heal and/or health pots you can use ignite to cut the health that they receive in half. Teleport: Helps you get back to your lane faster, gank other lanes, and even helps you teleport into a team fight.

I start off with Sapphire Crystal because Morgana needs that mana early game. (You can get health pots too if you want.) Sorcerer's Shoes are good if they are building Magic Resist. If they are not build magic resist feel free to to change them to Ionian Boots of Lucidity. Then I upgrade Sapphire Crystal to Catalyst the Protector followed by Tear of the Goddess. Next I go for Rabadon's Deathcap then upgrade Catalyst the Protector to Rod of Ages. You can either go for Ryali's Crystal Scepter or Archangels. (I wait for Archangels so I can get more mana stacks which means more AP :D). I close out with Zhonya's Hourglass for more AP and armor. (If you don't like the items I get change it up a bit!)

To farm use your "w" (Tormented Soil) a lot.

Morgana: Solo Top
Lee Sin: Jungler
Lux: Solo Mid
Taric: Bot
Irelia: Bot
