Ok she is really expensive tho isnt she?
Morgana is 1350 ip
Morgana's E is quite useless to be honest, it's the last thing I level up. It practically gives your teammates a small shield (around half of barrier) for no more than 5 seconds.
Unless you're vs TF lol, what's a stun?
And let me give my 2 cents. For new players, Nasus is good because he can be really,
really tanky lategame and still does a lot of damage (that is if you have farmed a lot and got your Siphoning Strike up).
Now, let me run through his abilities.
His passive, innately gives him lifesteal (it was around 20% before his Visual Update, I'm not sure about now).
His Q, Siphoning Strike. Has a scaling that increases for every stack of Siphoning Strike. To get these stacks, you have to kill minions, creeps or champions with Siphoning Strike. Killing small creeps and small minions gives 3 stacks. 6 stacks is given if you kill champions, large creeps (Ancient Golem, Elder Lizard, Dragon & Baron) or large minions (Siege minion, the one with the cannon). This means, if you farm like madman and be efficient with your farming and end up having like 300cs by 40 minutes. Your q will
literally melt their carries.
His W, Wither, decreases the attack speed and movement speed of his target over time. This allows him to easily land a Q during laning. However, it costs a lot of mana from his mana pool and one should never spam it. It deals no damage. This ability is especially good vs auto-attack reliant champions such as Vayne.
His E, Spirit Fire, is an AOE that deals damage over time and decreases the Armor and Magic Resist of those caught in it. This is stupidly good in teamfights as it shreds their defenses if they're clumped together. This ability also gives him the ability to push lanes by a huge margin. In conjunction with his ultimate, this ability is even better.
His ultimate (R), Fury of the Sands, makes him grow in size and increases his current hp and Bonus HP temporarily for 15 seconds. It also deals damage over time to those around you, caught in the sand. This gives him a good survivability and at the same time makes him flip faces.
Overall, Nasus is good because he teaches players why you should farm and he has a few failsafes (such as using your ultimate to run away when you're low).
Another good champion I recommend is Tryndamere. Why? Everyone in the lower levels almost
always fights him when he has his ultimate on.
For Skill order, if you're versus someone with crazy pushing power like Riven, max your E. If you're against someone that's squishy (low base armor and MR), max your Q. If you're somehow against Vayne or Jayce top, put a few levels (3, at the most) to your W. If you're against a tank like Malphite or Shen, max your Q and just farm. Try to avoid fighting when they start to get some armor up.
