Rumble

,  is a champion in League of Legends.

Abilities
Rumble's abilities have no cost related to them, and the use of his abilities is only limited by cooldowns. Instead, he uses Heat as his secondary resource. Rumble starts with 0 Heat, and it caps at 100.

Rumble's basic abilities generate 20 Heat when used. When Rumble reaches 50 Heat, he is in the Danger Zone, causing all his basic skills to have enhanced effects. When Rumble reaches 100 Heat he overheats for 6 seconds; during this time he may not use his own abilities, but all his basic attacks deal additional magic damage. While not overheated, after 4 seconds of not using his basic abilities he will start losing Heat at a rate of 10 Heat per second, then at a rate of 20 Heat per second 2.5 seconds later.
