Hi guys! I've been playing Morgana for a long time, actually she was the first champion I liked to play I have 132 755 maestrial points on her so I thought I could share my experience with other players. I hope that my guide will be helpful for new Morgana players.

Why you should start playing Morgana?

Let me give some reasons:

she is very useful for your team(black shield, long CC)
she is very easy to play
she has long range of her abilities so you can play very save
she is doing much damage

Also Morgana is the only champion who can give CC resistance from her Black shield, you can save your allies from imminent death, they will love you for it!

But like every champion Morgana has advantages but also disadvantages such as:

low hp
long abilities CD

Morgana's abilities

Passive

This ability gives heal to Morgana from 20% damage from her abilities during to large monsters, champions and large minions, that's big threatment so when I have low hp and I'm throught the jg i use my Q and W on large monsters to heal myself a bit.

Q

This ability CC time is extending while we max it, so I think that's should be our first max ability.
Don't waste your Q qhen you know that you can't hit for example when enemies are behind enemies minions or when they are to far, if you are playing against mobile champion like Vayne or Lucian , and you know that hit Q will be hard because they are saving their dashes specially to pass your Q you can position yourself to hit but don't using this ability to make presion to hamper enemy ADC with farming. If everything goes wrong and you are playing more defensive save Q for this moment when they going to atack for example when enemy supp is positioning to give you CC.

W

This ability cost so much mana and it not doing good damage when enemy can get of off this so use it when he gets CC.
Watch out where you use it because you can take farm from your ADC, you can also help him with push when opponents weren't on your line.
Somethimes I use it when i can't hit Q to make gold from .

E

Morgana's shield is so useful but it has long CD so save it for dangerous situations like enemy's gank or when your allie gonna have CC or magical damage, but remember this ability not save from physical damage.

R

This ult gives damage 2 times if enemies won't escape from our ult range and gives them CC. You can use ult on every enemy champions by single use. Your R also reveals enemy champions in range so you will see there in bushes. You can also use R when are invisible champions like Evelynn is near to you and reveal him.
