Malzahar, The magician of the void
Hello, this is my build for malzahar, my main champ.

For runes, focus on AP and Magic Pen. You can take the AP per lvl for greater AP amount late game, but i prefer taking the getting 30AP from the start, so that i can get myself fed at mid.

For masteries, we go 9-0-21, Focus on Mana regen, Running speed, and cooldown. the flash mastry if you have flash.

OK, so Malzahar is a mid character, or a solo top one, when you are at mid, use your E to farm like no one else, harass your opponent with Q so that they keep distance, and when your ulti is ready, Q>E>R and he's dead, try to make your voidling attack with you, if you do that, then 1600 gold is a piece of cake, go home, take your 80 AP and make the mid rage quit.

I focus on the visions, for farming and for it's ability to transfer and return mana, after it come the Q for that it does double damage ( there are two attacks on the Q so it's 300 + 300 )
but lvl your W once or twice mid game, for it's great damage if combined with ulti.

as for your combo, go Q-E-W-R and if you want to guarantee the hot of your Q, then wait for the opponent to attack you first, most people stay in one position to attack, so most the time they won't move for a while if they attacked you.

Pros
1 : Deals Huge amounts of damage
2 : he has two AoE spells
3 : a good farmer
4 : deals % damage to tanks
5 : his dance is so great xD

Cons
1 : he have no GTFO mechanism except for flash ( be careful when it's on cd )
2 : If you're running away with your pet on, he'll be a pain in the *** because you can't control him. and he'll show the foes your location.
3 : There's no 3

so easy, let the tank charge, they focus him for 2 seconds, you Q-W their whole team, put E on lowest one, and ulti another, GG
