Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Morgana the Spell Succubus Queen
My build is very easy you just need to not suck at using Morgana,This build is focused on using her passive to the fullest wile keeping her spells strong and keeping her semi tanky by lev 14 you should have about 50% spell vamp and with the AP you really see your HP gain from spell vamp in team fights.
first off I start with a Doran's Ring and a HP pot so your set really good early game with survivability HP/Mp regen and some AP for spell power. I normally play with a partner if you do as well start with your bind if solo soil.
Really early game is just you making enuf gold to start building into your Zhonya's ring as soon as you get your ring you will be able to handle team fights even better I love to run in the middle of the group use my uls and as they try to focus me I use my ring the ult will do 2nd burst wile ring is active.
2nd main item would be Will of the Ancient it helps your passive a lot making you have 50% spell vamp it helps party and this items stacks with others who use the item so if anyone gets one on your team you will have 65% spell Vamp and that is a burn with all the Ap this build has.
End game the items change for me depending on what I think I need but I normally end up with a Void Staff for more AP+magic pen and Guardian Angel or Banshee Veil for more survivability
