Not Updated For Current Season
I started playing LoL around 3-4 months ago, and Morgana is one of the first characters I fell in love with. She has good support, great damage, a very strong defensive shield, and her passive keeps you in a lane forever. I enjoyed playing her so much that I got pretty good at it and decided to make a guide for who, in my opinion, is one of the strongest AP carries.
Ignite and Clarity are by far my favorite summoner spells for Morgana. Ignite is invaluable for both its damage and healing reduction. Clarity combined with Morgana's passive ( Soul Siphon) can keep you in the lane forever. I have played many games where I have been mid for the first 15mins and made the other teams mid go back 3+ times. If you feel like you really need it Ghost or Flash could replace ignite, but the damage loss is noticeable.
Runes + Masteries
Runes are somewhat self explanatory, just enough magic pen in combination with the boots to get 30 magic pen, and then full AP per level.
Masteries are just a basic caster build.
The most important thing to remember for your skills is to rush level 3 Tormented Soil. At level 3 it is strong enough to completely wipe out the caster group of each wave. Every single wave you should place Tormented Soil between the two groups so it hits both of them, if they are too far apart and you have to choose always choose the caster group.
NOTE: If you place the Tormented Soil and then run far away you will still receive experience and gold if the TS kills a mob, so always throw out a Tormented Soil on your way out of a lane.
After level 3 Tormmented Soil getting Dark Binding to level 5 is your priority. It does more damage than Tormented Soil and does it in burst.
Although Morgana's shield is very powerful at higher levels, the damage you miss out on is way to big. At lower levels her shield should be mostly used to block any sort of Crowd Control. As long as the shield holds you are immune to Slows, Snares, Stuns, Blinds, Immobilizes, Suppresses, pretty much everything.
NOTE: Holding Alt and pressing E will auto cast the shield on yourself, the .1 seconds you save from this could easily save your life. If you hold Shift and press E it will auto cast on whoever your mouse is hovering over, mostly used in team fights.
Mejai's Soulstealer works really good with Morgana, with her snare and AoE spells she racks up a lot of assists as well as kills. If you don't feel to comfortable with a Mejai's (meaning you dont think you can keep it above 10 stacks) then just start off with a Doran's Ring and after everything else is completed get an Archangle's Staff.
Rod of Ages will help you with both AP as well as a bunch of health and mana. With Rod of Ages alone Morgana gets up to almost 2900 HP, enough to keep you up even when being focused.
Frozen Heart provides some much need Cooldown Reduction, and some decent mana and armor.
Zhonya's Hourglass works really well for Morgana, and more specifically for her ultimate. If you use your Ultimate and then use Zhonya's the second part will still go off while you are immune to all damage. This is a huge asset to teams fights as you can shield you self and walk in, hit your ultimate and then Zhonya's. While their team is focusing you and doing nothing, your ultimate is doing great damage, slowing, and then stunning them for you team to pick off the carries.
NOTE: The Elixir of Brilliance works really well with Morgana. Mid to late game you should purchase one every single time you go back to the base. After getting Frozen heart an elixir is all you need to be capped at 40% Cooldown Reduction. .2 seconds off of your snare and shield could easily save your life, or take someone else's.
The healing from Morgana's passive is nothing to sneeze at. Early game it is sometimes good to use Tormented Soil on a group of minions just for the health regen. Mid to late game it is sometimes worth it to turn around and throw out a Dark Binding for and instant 200+ life.
To get the most damage out of you combo you have to use Tormented Soil first. What I like to do is use Tormented Soil and then immediately after casting it use Dark Binding.
WATCH YOUR ENEMY. If they tend to run in the same direction every time you try to get them with Dark Binding throw it slightly at an angle in that direction.
Dark Binding + Tormented Soil + Soul Shackles + Ignite will burst down most carries.
If you are in a team fight to try use Dark Binding on and enemy champ that is separated from the group or on anyone while their team is running away. The snare gives your team enough time to catch up and pick off that person before their team can come back to save them.
If they are playing aggressively then they will be sure to go after you when you have low mana. Use that to your advantage! Bait them in and as they are on you use clarity. You can instantly turn around and throw out a combo with your ultimate and kill one of them.
Since Morgana is free as of this writing I hope you all will consider giving her a shot. With her high health pool and shield she can take a couple hits and still escape perfectly fine. If you get an enemy carry in a Dark Binding + Tormented Soil combo it will easily take you 1/3+ of their life. All in all she is a great AP carry that can take a beating!
Also since this is my first guide please feel free to suggest anything I could do differently!
