I play Morgana with a void staff and it is very useful and since you had said LB gives you that extra basic atack hit Void staff takes care of that and hurts the enemy more. Also noticed the you RoA is very late in game You should try and get that a little bit earlier so you can survive when you want to take on and enemy.

item list changed :D

i usually get them second right after majai's.... should probably change that

dude , really sucky build ! .. boots as last item? ... no mana regen or +mana item ? ... pleeease limit your builds to yourself

Thanks for the deathfire tip. I really didn't know which item to take after chalice, soulstealer and sorcerers boots.

i agree completely, this is why i asked for comments. i did say if you had the chance but i do see what you are saying, i forgot i had clarity up there thank you for pointing that out. your flash idea is great i wish i thought of that before. i will be adding and editing the guide as i go so please if you have anymore tips to help complete this guide im all ears

"for early game i recommend the tomb and the health pot"

a typo :) but a nice one. Take a tomb with you since you will die soon? :>

From my expirience.
You write: "you should have enough mana regen from your masteries and runes." but still take Clarity.
Yes i cant deny that this is a great spell to stay in lane for longer time but i would suggest getting flash instead. Why? so you could flash through line of mobs and catch someone with prison. And it is a more versitale spell in late game when you wont have any problems with mana at all.
About your Deathfire Grasp tactic. I would suggest doing it after prison landing on the champ. Your spells are DoT's, so it doesnt matter much if you do it DFS->Prison->Soil or Prison->Soil->DFG. You dont have the "initial damage spell" so it would be a waste of cd if you run to som1 to put DFG on him and than he runs away wouldit it?
