Build and Runes
Quickly get out of Rumble’s ultimate AOE zone as it deals massive damage per second.
Watch Rumble’s heat bar – he will be silenced if it becomes full. Take advantage of this as he’ll only be able to auto attack during this time.
Building Magic Resist will fair well against a Rumble because he only deals AP damage.
Don’t underrestimate an Overheated Rumble early, because his auto-attacks still do high damage.
