This my first time writing a guide for a LoL champion. I am not really that much of a tenured LoL player, I have only been playing this game for the last 3 months. I was having some difficulties at first with choosing a right champion on which to focus my gameplay. I tried everything from support's to carry, you name it, until I came across Malphite, which was by mistake I must say, just clicked random while he was free. I kept playing and playing him, and I noticed he was one of the most efficient champions to be played in the game; let me tell you why exactly :

-First of all you have extremely powerful harassment potential; With this specific build you can spam your Q like crazy, and eventually jump for the kill without even using your flash for it, the speed boost from the Q will allow you to chase down most champions and Ignite will prove very useful early-game for getting ganks. You may consider these ganks to be useless for a champion like Malphite, but you'll see that this guide is for a very aggressive play.

-Secondly, you are also a GREAT initiator for team fights. Your R is superb for catching squishies who want just a little bit too much harassing before the team fight; You can even use it for solo ganks, simply going with R W E Q + Ignite combo, this will guarantee you a kill.

-Third and most important is the potential farming ability for a tank. Keep in mind that Malphite is NOT a jungler, but you have farm like crazy mid and late game with W and Sunfire Cape.

Pros :

-Great farmer
-Excellent ganking ability
-Great initiator
-Great chaser

Cons :

-Squishy early game (Compensated by runes)
-Mana dependent
-Mana dependent
-Mana dependent
-Mana dependent

I have chosen to compensate the early-game vulnerability instead of the mana issues with runes/masteryes due to the fact that you do get the Philosopher's Stone and also you can pop a mana potion and still keep harassing eary-game.

My runes choice is simply

Marks :Greater Mark of Insight

The choice for this is obvious. Since you will be spamming Q like crazy early-game, this will prove to be CRUCIAL to getting your opponents low. The difference is very noticible. it will also prove very efficient when ganking.

Glyphs :Greater Glyph of Warding.

Seals :Greater Seal of Resilience

Both these runes are for early-game resistances. Trust me, they will prove their worth.

Quintessences :Greater Quintessence of Fortitude

Health is also useful for a tank, so it was the obvious choice.

Flash
This ha been proven very important in engaging fights, escaping and of course ganking. I wouldn't recommend going without this but if needed, there is also a different option to go about.

Ignite
