Rumble's abilities have no cost related to them, so the use of his abilities is only limited by cooldowns. Instead, he uses Heat as his secondary bar. 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 abilities to have enhanced effects. When Rumble reaches 100 heat he overheats, silencing himself for 6 seconds after which he will cooldown completely. While not overheated, after 4 seconds of not using his basic abilities he will start losing heat at a rate of 5 every half second, and 2.5 seconds later at a rate of 10 every half second.

Abilities Edit

Patch v1.0.0.144
Junkyard Titan	(Innate): When Rumble reaches 100 heat he overheats, silencing himself for 6 seconds to cooldown completely and causing his basic attacks to deal an additional 20 + (5 × level) + (0.25 per ability power) magic damage for the duration.
Junkyard Titan is a passive ability. When Rumble's Heat meter reaches 100, he cannot use his champion abilities for 6 seconds, but his autoattacks will deal additional magic damage. After the overheat is over, heat is reset to 0. Although the silence animation is used, Rumble can still use Summoner Spells and active item abilities while overheated. Only his own spells are disabled. The ability disabling cannot be prevented or blocked at all and its duration cannot be shortened by any means. Rumble's auto-attacks when overheated do not proc spell vamp or Rylai's slow. Autoattacks when overheated will damage Black Shield. Only the magic damage is blocked. Autoattacks when overheated do not pop Spell Shield. The magic damage from Junkyard Titan is not applied to structures, such as turrets. If Electro-Harpoon causes Rumble to overheat, he may still cast and use the second harpoon even if silenced.
