- It's important to keep a close eye on your heat gauge whenever casting, with the exception of The Equalizer. All of Rumble's abilities are stronger from 50% heat to 99% heat, but overheating (at 100% heat) will silence you.
- Spam Flamespitter at the beginning of the game to get in the danger zone, increasing your damage.
- The bonus damage on Junkyard Titan can be just enough for the kill, but be careful, because if you were relying on one of his standard abilities to help you pick up the kill, the silence due to overheating can end up denying you a kill.
- Consider leveling Scrap Shield for a low cooldown movement speed boost, and an effective clutch shield.
- Electro-Harpoon and The Equalizer help to keep foes within range of your Flamespitter.
- The Equalizer receives no benefit from being cast above 50% heat, so it can be wise to cast early so that you don't risk being overheated when you really need The Equalizer.
- Proper placement of The Equalizer can completely change a teamfight. Depending on where it is placed, Rumble can punish enemies attempting to enter a teamfight, damage most enemies already within the teamfight or cut off the escape route of enemies wishing to exit the teamfight.
- Scrap Shield and Electro-Harpoon both have utility for chasing/escaping.
- Rumble is one of the few "mage" type units whose standard attack is a melee range attack which will put him in harms way very often. Buying items that increase health like and or increase resistances like and can be very helpful.
- Scrap Shield increases your effective health (and scales with ability power) so buying items that increase your resistances (and ability power) like and can improve its effectiveness.
- Since The Equalizer and Flamespitter do damage the longer an enemy stays within them, a can help prevent foes from moving out of Rumble's damaging AoE.
- Because Rumble scales so well with ability power, is highly beneficial to him.
- The bonus damage from Junkyard Titan has a 0.3 ability power ratio per attack. If you find yourself relying on Junkyard Titan for damage output, building lots of ability power with some attack speed (like you might find on ) will augment your damage output while giving you ability power and magic resistance reduction for your abilities.
- Spell Vamp items like and help Rumble stay in lane longer, alternatively health regeneration items like also help him.
- Although Rumble could benefit from cooldown reduction, very few cooldown reduction items have any synergy with him. Therefore, and are beneficial.
- Because he is manaless, Rumble is one of few champions able to indefinitely keep stacks on outside of battle at no real cost. The item offers a significant offensive boost to Rumble, particularly while using Junkyard Titan.
- Because Rumble is a semi tank, you may buy items like Force of Nature or Zhonya's Hourglass to build up your tank. You may also choose to buy Sunfire Cape to deal damage while you're fighting as you would be near to the enemies when you uses Flamespitter.
- Rumble deals primarily magic damage. Get magic resistance items to reduce his damage output.
- In lane try to wait until Rumble uses Flamespitter and/or Scrap Shield before taking the offensive. This will help tilt skirmishes in your favor.
- Flamespitter is a powerful zoning tool but it pushes the lane, so try to get an ally to help gank Rumble.
- It is wise to wait until Rumble overheats and silences himself before engaging him.
- Moving away from his The Equalizer can be critical to your survival. Avoid tight paths which will make moving away from it impossible along the path. Remember that it has a very high potential range.
- Be careful after avoiding his Electro-Harpoon, as he can still fire another one even if he overheats.
