Mana Regen Extremes: Karma's 13 Towers Over a 16-Way Tie at 6, Ezreal Ties For Fastest Growth

I checked base mana regen (MP5) across all 145 mana-using champions. The gap between the highest and lowest value at level 1 comes out to 2.17x, and while the bottom tier of 6 is a 16-way tie, the top spot belongs to Karma alone at 13.

So what is MP5, anyway

Mana in LoL slowly regenerates on its own even if you do nothing. The regen rate is the sum of a base value and a per-level growth value, and since it's measured per five seconds, it's called MP5. Same mechanic as HP5 on the health side, just for the mana bar. Of the full 173-champion roster, 145 run on mana; the rest use energy or unique resources instead.

Base value: Karma stands alone at the top

Base MP5, highest	Value
Karma	13
Nami	11.5
Janna	11.5
Kayn	11.5
Lillia	11.5
Milio	11.5

Five champions tie for second at 11.5, but Karma sits alone at 13. Her kit leans hard on mana-fueled utility spam, so a base built to let her cast freely from minute one tracks.

The bottom tier: 16 champions, no pattern by role

At the other end, the minimum of 6 is a flat 16-way tie. Tanky supports like Thresh and Leona sit next to ADCs like Jhin, Zeri, and Sivir, next to assassins like Shaco, Kassadin, Nidalee, Elise, and Fizz. I couldn't find a role-based explanation for who lands here. Looking at the raw numbers, it almost feels arbitrary.

Fastest growth: 7 champions, an unexpected lineup

Growth per level	Value
Ezreal	1.0
Jinx	1.0
K'Sante	1.0
Naafiri	1.0
Pyke	1.0
Ryze	1.0
Tahm Kench	1.0

Ezreal and Jinx, the two ADCs constantly memed for running dry on lane, tie for the fastest mana regen growth in the entire 145-champion pool. They start out unable to keep pace with anyone else, then claw all of it back by the late game. K'Sante and Tahm Kench, both tanks, sit at the exact same rate, so growth rate clearly has nothing to do with role.

By level 18, Kayn, Lillia, and Seraphine take the lead

The final standings look nothing like level 1. Kayn, Lillia, and Seraphine all land on 27.65, tied for first, edging out Karma's 26.6 despite her early lead. Karma's growth rate is a middling 0.8, so her level-1 head start alone wasn't enough to hold the top spot.

There's movement at the bottom too. Shaco, already tied for last at level 1, also has one of the worst growth rates in the game at 0.35, and ends up alone in last place at 11.95 by level 18. Darius shares that same 0.35 growth rate but started slightly higher, so he narrowly avoids last place, settling at 12.55. Neither champion leans on mana much to begin with, so landing here isn't surprising.

Takeaway

Mana regen barely tracks with how a champion looks on paper. Ezreal and Jinx, the poster children for running out of mana early, end up tied for the fastest regen growth in the game, while some tanks and supports settle near the bottom instead. A lot of translated blogs stop at just listing the stat. You don't get the real payoff until you see the lineup completely flip between level 1 and level 18.

Finding out Ezreal ties for the fastest mana regen growth in the league made me regret every ability I held back on lane
