Mana regeneration

Mana Regeneration (also known as Mp5 or mana per 5 seconds) is a statistic that determines the amount of mana that a champion regenerates over a five second period. Each champion starts with a certain rate of base mana regeneration. This statistic scales additively; meaning that each bonus point acquired directly affects the statistic. The player can also use

Clarity (a summoner spell) to restore mana.

In Dominion mode, mana regeneration is increased by 2% per 1% mana you are missing.

Trivia Edit

The greatest mana regeneration currently possible is 2327.01, achieved by Evelynn. To reach this amount, she must:

Have reached level 18 in the last 7 seconds.
Have 4 fully farmed Archangel's Staves.
Have an Athene's Unholy Grail.
Have a fully grown Rod of Ages.
Be affected by a Soul Shroud aura.
Be affected by a Mana Manipulator aura.
Have 3 points in the Expanded Mind mastery.
Have 3 points in the Meditation mastery.
Have 9 marks and 9 glyphs of Knowledge.
Have 9 seals and 3 quintessences of Clarity.
Be stealthed thanks to her passive Shadow Walk.
Be consuming a Mana Potion.
Be affected by the Crystal Scar aura (and so, being playing Dominion).
Have zero mana left.

This makes a total of 2327.01 mana regeneration, as shown below:

(17.9 + (25 × 4) + 15 + 125 + 12 + 7.2 + 3 + 33.33 + (1.17 × 9) + (4.32 × 3) + ((936 + (400 × 4) + 1000 + 725 + 216 + (21.06 × 9) + (25.56 × 9)) × 0.05)) × (1 + 1 + 2) = 2327.01

In case of being playing in the Summoner's Rift, the maximum mana regeneration is 1595.54, also achieved by Evelynn. In this case she can't be affected by the Crystal Scar aura, but she must (along with the previous conditions):

Have one fully farmed Archangel's Staff instead of 4.
Have 4 fully grown Rod of Ages instead of one.
Have 9 seals and 3 quintessences of Knowledge instead of Clarity.
Possess the Crest of the Ancient Golem.
Possess the Exalted with Baron Nashor.

The math in this case is:

(17.9 + 25 + 15 + 125 + 12 + 7.2 + 3 + 33.33 + 25 + ((936 + 400 + 1000 + (725 × 4) + 216 + (21.06 × 9) + (21.06 × 9) + (25.56 × 9) + (75.06 × 3)) × (0.05 + 0.025 + 0.01))) × (1 + 1) = 1595.54

However, it has to be noted that the values won't be maintained for longer than half a second (since the % increases depending on missing mana will decrease). That taken into account, the highest mana regeneration per half second is 232.70 in the Crystal Scar, and 159.55 in the Summoner's Rift.
