Intro
Jungling Malphite has alot of positives over Warrick or any other jungler, of which I shall list. Keep the following in mind.
The Positives
1 - Not Dependant on Damage or AP. Like Fiddlesticks he is not dependant on Damage or AP to jungle.
2 - Low Risk. Unlike other junglers you are a Tank Hero and ganking you will be extremely hard for anyone todo. Granite Shield recharges between camps lowering the overall damage you take by a ton.
3 - Better Team Presence. Once you leave the jungle you have at your disposal a Ranged AoE stun that puts you in a tanking position, a spamable -Attack speed debuff and a single target slow, and they HURT =P
4 - You Overpower other junglers. If you happen to find yourself 1v1 at level 1 vs another jungler you will win. That simple. Only 1 who "might" cause you trouble is a Fiddlesticks, but not if you dodge his lifeleeching ability before you start pounding on him. The non caster junglers of Rammus, Jax, Blitzcrank and the "so called best jungler" Warick will cower in fear. If Warick is a king, Malphite is an Overlord.
The Negatives
1 - Dependant on Smite. Without smite jungling will be very hard for you early on, as your damage output without the Golem Buff is very low.
2 - Dependant on Golem Buff. Without it, You cant spam Ground slam meaning you cannot kill neutrals meaning you cannot jungle. If you do not have the Orge buff you will be forced to lane as you will jungle too slow, even if you use Mana Potions.
3 - Cannot Solo Baron. So dont even try it! =P
The Basics
Starting Items
1x Elixir of Fortitude
5x Health potion
Elixir of Fortitude is essential to jungle with. It practically doubles your HP which also doubles absorbing power of Granite Shield. The health potions are mainly to keep your HP up, you will be tanking the neutrals to jungle and have no way to recover health through skills like Warrick and Fiddlesticks. Feel free to Gank or assist and use a Health Potion or 2 afterwards, normally you will use only around 3 when you jungle.
Recommended Runes + Masteries
9/0/21 is staple, getting the -9% cooldown from masteries and then filling up with the remaining 6% from runes, giving you the max of -40% when you slay the golem. This reduces your Ground Slam cooldown to 4.8 seconds, which is essential to farm with, as it is your main source of damage and it improves your Effective Hitpoints as it makes neutrals attack you slower. Dodge also helps alot, you should be able to get 11% or so from runes if you use all 9 + Quitesence.
Recommended Summoner Spells.
1 - Smite - THIS IS A MUST. Without smite, I would not recommend going to jungle.
2 - Heal - You are tanking neutrals so you will be taking alot of damage, this also helps protect you against ganks.
3 - Rally - Not as Good as Heal IMO as it is not instant and you are not dependant on Physical damage to kill neutrals. However it is still good and does allow you to have a better team presence.
4 - Ghost - Does not help you jungle, but can be very useful in escaping ganks and ganking.
Skillbuild
Take Ground Slam at level 1, Brutal Strikes at level 2. For level 3 onwards the priority is to Max Ground Slam followed by Sesmic Shard, taking Unstopable Force at level 6-11-16. Brutal Strikes level 1 is taken early on because it is cheap to use and 30% extra damage 66% of the time for 55 mana is a bargin, not the mention to the 30% cleave. However after getting 30% at level 1 the Cleave + damage boosts scale by only 5/10% per level and the mana cost goes up a ton, hence this skill is maxed last.
Items of Choice
Up to you. I strongly advise Sunfire Capes, as they improve your Tanking presence and synergise very very well with your skillset and role as a tank in general. You do NOT need to buy Madreds Razors, so do not waste your gold on one, you will barely notice the difference.
Basic Jungle Procedure
Spam Ground Slam, keep your HP up, use Brutal Stikes when you have the spare mana. Don't forget to let your Granite Shield recharge Between camps. Start with the Golem, then work your way around. You should be able to kill every neutral camp at least once before your elixir wears off without any problems, including the dragon. After level 6 gank whenever Unstopable Force is off cooldown.
Ok Any questions? =P
