Even amongst yordles, Rumble was always the runt of the litter. As such, he was used to being bullied. In order to survive, he had to be scrappier and more resourceful than his peers. He developed a quick temper and a reputation for getting even, no matter who crossed him. This made him something of a loner, but he didnâ��t mind. He liked to tinker, preferring the company of gadgets, and he could usually be found rummaging through the junkyard. He showed great potential as a mechanic. His teachers recommended him for enrollment at the Yordle Academy of Science and Progress in Piltover, where he may very well have become one of Heimerdingerâ��s esteemed prot�©g�©s, but Rumble refused to go. He believed that Heimerdinger and his associates were â��sellouts,â�� trading superior yordle technology to humans for nothing more than a pat on the head while yordles remained the butt of their jokes.

When a group of human graduates from the Yordle Academy sailed to Bandle City to visit the place where their mentor was born and raised, Rumble couldn�t resist the temptation to see them face-to-face (so to speak). He only intended to get a good look at the humans, but four hours and several choice words later, he returned home bruised and bloodied with an earful about how he was an embarrassment to �enlightened� yordles like Heimerdinger. The next morning he left Bandle City without a word, and wasn�t seen again for months. When he returned, he was at the helm of a clanking, mechanized monstrosity. He marched it to the center of town amidst dumbfounded onlookers and there announced that he would join the League of Legends to show the world what yordle-tech was really capable of, without hiding behind a foreign banner.

�Ugh, it�s gonna take forever to scrape your face off my suit!�
- Rumble

This is my first build. So any advice is welcome. Please try the build before you vote it down.
I like to have rumble a bit tanky so he can take a hit and tower dive easy, while giving him AP to get his dmg at a nice level.

Again, I take the standard mage masteries in offense and then put 21 points into defense to help keep him a bit tanky.
Picking this path will bring you more armor/magic resist, more AP, and more health.

Putting 21 points into utility works to if you wish to go that path.
Going this path will bring you more gold, faster movement speed, more exp to get to level 18 faster, and shorter cooldowns of your summoner spells.

The summoner spells I feel are the only ones that work with Rumble.

Ghost: Rumble has a speed boost from him shield and 2 slows. Paired with exhaust, the enemy will stay in range of you the whole time without ghost.

Flash: Same thing as ghost. You have a speed boost and 3 slows, Flash is just overkill imo.

Teleport: This can be taken over exhaust if you like. It works well to get around and get those tower saves in fast or that push.

Revive: you really shouldn't be dieing that much as rumble. He has great defence and is easy to get away with. Just use your Scrap Shield for the speed buff, if they are still close on your tail then use The Equalizer to slow them down or use Electro-Harpoon.

Clairvoyance: Waste of a spell. This will not help you at all.

Rally: Another waste of a spell.

Clarity: You don't use mana.

I like to start out with tanky items so that I can survive the team fights and being ganked (having tank items is nice with you are ganked by all 5 people because you have several kills).

The AP items will boost your Dmg. Rumble has high base Dmg so he needs little AP.

Potions are not needed most of the time imo, but if you wish to take some for early game you can.

Pros:
-Great AoE damage.
-Great CC in the way of numerous slows.
-Great battlefield control in the way of his ultimate.
-Great survivability when used properly.
-Can switch from a ranged AP harass to a melee powerhouse simply by spamming his skills, allowing for the easy finish off.

Cons:
-Cannot utilize mana items, runes, and masteries to their full extent.
-Melee AP damage requires you to be up close and personal with your enemies, potentially leading you to sticky situations.
-Dealing burst damage requires the enemy team to be oblivious enough to stand in your ult, or a team smart enough to CC them in your ultimate.

As rumble it is very easy to farm. Just spam your flamethrower and the minions will drop like flies.

Jungling is not recommended with Rumble. If you can get in top or bottom lane with a range champion.

When playing Rumble always remember you are not the tank.
Yes you have high health.
Yes you have a sheild.
Yes you will drop fast if you attempt to tank.

When in a team fight let the tank go in first (or whoever is dumb enough to run in before the tank) before u start attacking.
Once the enemy as switched their focus to someone else then start spamming your flamethrower.
If someone tries to run hit them with your harpoon. If that is not enough then hit them with your Ult and they will drop.

If you get focused, hit your shield and back up. If they chase you do the same thing, hit them with a harpoon or Ult and keep spamming that shield for the speed buff.

These are just a few of the games I have played using this build.

Rumble is the best hero I have played so far. He is fun and has a lot of utility. Give him a try and a promise you will not be disappointed.

I hope you enjoyed my guide. Please try it before you vote it down. Also please leave a comment as to why you vote it up or down.
