Spirit In World of Warcraft . Creatures . Spirit is a somewhat generic name for an undead creature . Most unspecified spirits are similar to ghost s , shade s , or spectre s . Attribute . In the " World of Warcraft " , the Spirit character attribute regenerates Mana and Health . In most cases , health regeneration is suspended while in combat , while mana regen is interrupted after expending mana ( usually via spell casting ) . This is , for many class es , considered the worst possible stat ; however , spec ' ed priest s and druid s may find it useful as they gain increases in healing with increase in spirit . In addition , some talents and spells like an mage ' s and a druid ' s allow a portion of spirit based mana regeneration to continue while casting , making it a useful stat for sustained damage and healing in such cases . Warlock s also see increased damage and bigger with a 3 : 1 ratio of spirit to damage . 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 MP5 items , which is never interrupted for any reason ( see the mana regeneration article for details ) . Formula . Research by shows that since Patch 2 . 4 , mana regeneration is uniform across all classes and based on the following formula : Base _ Regen is a variable dependent on character level and can be taken from the following table : 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 : 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 : 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 . Temporary Buffs to Spirit . There are spell and consumable buffs to spirit . Not all stack with each other , and some are seasonal . Buffs ( divine spirit or scroll ) : Elixir ( you can have 1xBattle and 1xGuardian ) : Food ( food or drink ) : Seasonal : Molten Armor and Spirit . Starting with patch 3 . 1 , was changed to a Spirit dependent effect . Prior to that , it was a static increase to Spell Critical Rating . Without a glyph of Molten Armor , the conversion is 35 % of total Spirit into Critical Strike Rating . With the Glyph of Molten Armor , 55 % of Spirit is converted to Critical Strike Rating . For example , plus 60 to Spirit ( Molten Armor Glyphed ) would add 33 Critical Strike Rating . 33 Critical Strike Rating increases Spell Criticals by 33 . 00 / 45 . 91 or about . 72 % . In the RPG . 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 .
