Rumble

Innate: Rumble's ability casts generate Heat, which decays by Heat per second after not using any basic ability within 4 seconds or The Equalizer within 2 seconds. Rumble's mech enters the Danger Zone when at or above Heat, and becomes Overheated while at Heat.

Danger Zone: Rumble's mech enters the Danger Zone, empowering his basic abilities.

Overheated: Rumble's mech becomes Overheated, disabling his abilities as his Heat decays back down to 0 over 4 seconds. During this time, he gains 50% - 142.54% (based on level) bonus attack speed and empowers his basic attacks to deal 5 - 44.12 (based on level) (+ 25% AP) (+ 4% of the target's maximum health) bonus magic damage on-hit. The damage based on the target's health ratio is capped at 65 - 163.33 (based on level) against monsters.

Active: Rumble generates Heat to activate his flamethrower for 3 seconds, spewing forth flames in a frontal cone every 0.25 seconds. Enemies hit by the flame are scorched for 0.6 seconds, taking magic damage every 0.25 seconds as well as upon being hit if not currently scorched, refreshing on subsequent inflictions. Flamespitter's damage is reduced to 70% against minions.

Junkyard Titan 2 Bonus: Flamespitter's damage is increased by 50%. Flamespitter's total damage based on the target's health is capped at 65 - 336.84 (based on level) against monsters.

Active: Rumble generates Heat to grant himself a shield for 1.5 seconds.

Rumble also gains bonus movement speed for 1 to 1.32 seconds.

Junkyard Titan 2 Bonus: Scrap Shield's shield strength and bonus movement speed are increased in effectiveness by 50%.

Active: Rumble generates Heat to shoot a harpoon in the target direction that deals magic damage to the first enemy hit, inflicting them with magic resistance reduction for 4 seconds and slow them for 2 seconds. These effects stacks additively with multiple harpoons, refreshing their duration and stacking up to 2 times.

Rumble periodically stocks an Electro Harpoon charge, up to a maximum of 2.

Junkyard Titan 2 Bonus: Electro Harpoon's effects are increased by 50%.

If Rumble casts Electro Harpoon before his mech becomes Junkyard Titan 3, he may still use another charge within 3 seconds of the initial cast.

Active: Rumble deploys a barrage of rockets from the sky along the target path in a line over 0.75 seconds. Each rocket impacts the ground to create a field of fire that lasts 4.5 seconds.

Enemies struck by the impact or within the field are marked Burning for 1 second, taking magic damage every 0.25 seconds and being slow by 35%, refreshing while in the area. Enemies may be Burning for up to 5 seconds, for a total of 20 instances of its effect.
