D2R Energy

D2R Energy

Energy determines how much Mana your character possesses.

Mana is your character’s spiritual essence. Each time certain skills are used, such as the Sorceress’s Fire Bolt or the Barbarian’s Double Swing, some mana is consumed. Without items with Regenerate Mana +x%, or the Sorceress’ passive skill Warmth, your Mana pool will be fully replenished in 120 seconds (or 2 minutes), if it were completely empty at first.

Chance of Double Mana Regeneration
Your Energy determines your chance of receiving twice the normal Mana points from a Mana Potion:

Chance of Double Mana for Energy up to 200 if Energy is even: (Energy – 2) / 4
Chance of Double Mana for Energy up to 200 if Energy is odd: (Energy – 1) * (Energy – 1) / (4 * Energy)
Chance of Double Mana for 200 Energy and up: 100 * (Energy – 101) / Energy

The quality and type of potion used does not affect the formula.

Mana Regeneration Formula
The following formula is used to calculate how much Mana a character can regenerate per second:

25 * [[256 * max_mana / (25 * 120)] * (100 + %Mana Regeneration) / 100] / 256

Totals within the [ ] brackets are rounded down.

For example, with 900 Mana and level 20 Warmth (+258% Mana Regeneration), we regenerate 26.5625 Mana/second.

25 * [[(256 * 900) / (25 * 120)] * (100 + 258) / 100] / 256

25 * [[230400 / 3000] * (358 / 100)] / 256

25 * [76 * 3.58] / 256

25 * [272] / 256 = 26.5625 Mana/second

This simpler formula gives an approximation: (M * R) / 120. M = Maximum Mana
R = (100 + %Mana Regeneration) / 100

(900 * (100 + 258) / 100) / 120 = 26.85

Increasing your Mana (with items, for example) is a good way to increase Mana Regeneration.
