League of Legends Rumble players may find him to be a challenging character to build out properly. You will see that his build changes when he is fighting either diversified or homogenous team comps, demonstrating you shouldn't select the same Rumble build every single round of League of Legends
The best items to incorporate into your champion's build include: Hextech Rocketbelt, Rabadon's Deathcap, and Shadowflame. Those who added these items in their kits had a much better win rate than those who went for other builds for Rumble.
