Spirit

The source book for WoW Roleplaying game defines Spirit as the following: Spirit relates to common sense and the ability to perceive the environment. It gives a character the ability to look at a forest and find the tracks of a creature; at the simplest level it allows a character to know not to put his hands in the fire, else they will get burned. Any creature that can perceive its environment in any fashion has at least some Spirit. Those who survive by wit and intuition, such as healers and scouts, have high Spirit. ^{(WoWRPG 29)}

In the World of Warcraft computer game, Spirit is much more mundane. It regenerates Mana and Health. In most cases, health regeneration is suspended while in combat, mana regen is interrupted after expending mana.

Mana Regeneration

Five Second Rule

Whenever mana is expended for any purpose, mana regeneration is interrupted for five seconds. This is most often caused by casting spells, but diseases that drain mana will also interrupt mana regeneration. During this time, no spirit-based mana regeneration takes place unless the character has certain talents; there is also the fixed regeneration from mana/5 items, which is never interrupted for any reason (see the mana regeneration article for details).

Formula

Research by Whitetooth shows that since Patch 2.4, mana regeneration is uniform across all classes and based on the following formula:

 Mana Regen = 5 * (sqrt(Int) * Spirit * Base_Regen)

Base_Regen is a variable dependent on character level and can be taken from the following table:

Base_Regen

Base Regen Chart

In effect, the regeneration rate depends on Int, Spirit and character level. A 1% increase in Spirit increases mana regeneration by 1%, and 1% Intellect yields 0.5% more regen. This is a rough rule of thumb, but is accurate enough for most situations.

Intellect doesn't influence mana regen linearly, rather the square root of Intellect is used. This means that higher Int values yield diminishing returns, as can be seen in the following table:

Intellect vs Spirit Coefficient

Intellect	Spirit Coefficient	Needed Spirit for +500 mp/5
200	0.66	752
250	0.74	674
300	0.81	615
350	0.88	570
400	0.94	533
450	0.99	503
500	1.05	477
550	1.1	455
600	1.15	436
650	1.19	419
700	1.24	404
750	1.28	390

This chart shows the amount of mana/5 gained from one point of spirit, with a known Int score and for level between 60 and 70:

Mana Regen Chart

The moral from this table is that it's not a good idea to optimize Spirit at the cost of Intellect (or vice versa). Both stats need to be developed in a fine balance.

Health regeneration

There's currently no source for the exact formula for health regeneration. It's quite probable that it has been changed similar to mana regeneration. When it comes to endgame gear, spirit health regeneration is not a factor which deserves any consideration, as the amounts of health regenerated are very low compared to the incoming damage.

Note also that, with the exception of Trolls, no Spirit-based health regeneration takes place while in combat.
