Have you ever seen a rat in a coco-nut?
This is Rumble, Rumbling faces .
This guide will show you MY way of rampaging with it.
Believe or not,use or not, rate or ... rate.

As you probably saw, I build Rumble with tanky-AP stuff.
This is variable , But as a melee caster, i think it's one of the best way you can play it.(you can surely try boots + 3 Rabaddons + 2 warmogs but... wierd one, no?)

I do the rabaddon deathcap as a first item cause the early game is the part of the game in which you have less risks of being caught by fullstuffed guys and overpowered carrys.

Next comes the rod of ages, granting you bonus AP, Health, mana , on time, what do you need more?With a bonus of 1250 HP lategame with the whole build , including Rylai's scepter, granting HP, AP, AND a bonus slow soooo effective with your Q, you'll surely get the 3k2/3k5 HP full stuffed, with a bonus shield. This is quite good for a melee AP.

The other items are just giving you Mres Bonus, Armor Bonus, that you would want in every teamfight.

There's clearly no skill sequence for a Rumble as it can be for a Annie .

Every skill is casually used, except your Q you want to always keep up when surrounded or chasing ennemies.

When chasing,each of your skill is usefull : Q to kill, W to run faster, E to slow,R to slow again and do some DoT

In teamfights, just keep Q up, for damages,send R and try to get the maximum amount of players in it, and use W and E when needed , or randomly if you'r in panic (WARNING WARNING WARNING)

Try not to get in the red zone in early game, but lategame, in can pound off soooo easily squishy characters or carrys , use it well.
For my part, i just keep spamming and hurting the weaker, always a good idea cause the weaker often does most damages.

Attention: You'r not made for downing tanks, so don't focus them.
