| − | The condition of a game character gaining [[mana]] points over time is referred to as '''mana regeneration'''. Players can gain mana from basically two sources — [[spirit]] or items. Spirit regenerates rather high amounts of mana, but suffers from the restriction that it is interrupted for five seconds after spending mana for a spell (see 5 second rule below), while item-based regeneration is usually lower, but continues uninterrupted at all times. |

| − | The main base stat which regenerates mana is [[spirit]]. To a lesser extent, [[intellect]] also contributes, and the character level adversely affects regeneration. It's a good rule of thumb to assume that 1 spi = 1 mp5 while not casting. |
||

||
| + | ==Notes== |
||
| − | The above chart was generated using this data. The formula shows that regeneration increases linearly with spirit and with the square root of intellect. The base regeneration goes down as level increases. When analyzing the plot it appears that levels 1-10 have one curve, 11-60 another and 61-70 have a jagged but almost linear decrease which seems to have been tweaked by hand. |
||
| + | [[File:Northwatch Supply Crate and Northwatch Lugs.jpg|thumb|In Northwatch Foothold.]] |
||
| + | The Northwatch Supply Crates start out around {{coords|52.6|81.7|Durotar}} or so, and the Northwatch Lugs spawn at regular intervals. If left unmolested, they will form a chain of mobs between the spawn point and the encampments in [[Northwatch Foothold]]; however, if many players are killing them, they may be backed up, in which case simply wait at the spawn point on the shore. |
||
| + | The Lugs have a ridiculously small health pool (21 health) and are no challenge despite coming three to a crate. Be sure to strike them rather than having an ability like the druid's [[Thorns]] or hunter's pet kill them, as you will not receive credit. |
||
| − | Together these design elements seem to enforce balanced stats, so that stacking spirit to the detriment of intellect is to be avoided. It seems that 1 spirit = 1 MP5 was the target of the game designers. A level 70 caster needs about 460 intellect to reach this point. |
||
| − | == |
+ | == Quest progression == |
| + | #{{questlong|Horde|6|Breaking the Chain}} |
||
| − | After a character expends mana in casting a spell, the effective amount of mana gained per tick from spirit-based regeneration is reduced (''interrupted'') for a period of 5 seconds. This is commonly referred to as the '''five second rule''' ('''FSR'''). |
||
| + | #{{questlong|Horde|6|Purge the Valley}} |
||
| + | #{{questlong|Horde|6|Riding On}} |
||
| + | == Patch changes == |
||
| − | Channeled spells are handled a little differently. The FSR starts when the spell's channeling starts; i.e. when mana is expended. The interruption continues for at least five seconds, and longer if the channeled takes more than five seconds. For example, Mind Flay channels for 3 seconds and interrupts regeneration for 5 seconds (from the moment the spell cast starts), while Tranquility channels for 10 seconds and interrupts regeneration for the full 10 seconds, but not longer. |

||
| − | |||
| − | Multiple ratios do stack, but can never exceed 100%. |
||
| − | |||
| − | Spells which don't cost mana do not start the FSR. This includes spells with a normal mana cost of zero (e.g. [[Nature's Swiftness]]), but also spells whose effective cost is reduced to zero by some effect (e.g. by [[Clearcasting]] or an item ability or proc like [[Eye of Gruul]]). |
||
| − | |||
| − | Prior to [[Patch 1.4]] regeneration was also interrupted during a spells cast time (since then it's only interrupted when mana is expended). For this resaon, in-game textual references to the FSR still read "while casting" where they actually should read "after expending mana to cast". |
||
| − | |||
| − | == Direct regeneration == |
||
| − | Many effects increase mana regeneration directly i.e. without increasing spirit. These effects are governed by different rules than spirit-based regeneration, in particular they're never subject to the five second rule. |
||
| − | |||
| − | The most frequent source of non-spirit-based regeneration is the "regenerates X mana in 5 seconds" stat on items. This stat is usually written abbreviated as "mp5". |
||
| − | |||
| − | There are some effects which regenerate mana (e.g. [[Insightful Earthstorm Diamond]]) which deliver their mana the instant they [[proc]]. Some items (e.g. [[Second Wind]]) do not regenerate mana in 2 second ticks but rather in the intervals actually advertised in their tooltip. |
||
| − | |||
| − | Druids can gain direct mana restoration in proportion to their [[intellect]] with the [[Dreamstate]] talent. |
||
| − | |||
| − | ==Comparing spirit based and direct regeneration== |
||
| − | In theory, direct regeneration is preferable as it is not subject to the FSR. Unfortunately though, mp5 is much harder to get and more "expensive" than spirit. All attributes have an [[Formulas:Item Values|Item Value]], a kind of "cost" associated. This value for mp5 is 2.5 times higher than for spirit. For example the two top mana regeneration enchants for chest items yield either 15 spirit or 6 mp5 ({{loot|enchant|Enchant Chest - Major Spirit}} and {{loot|enchant|Enchant Chest - Restore Mana Prime}}) - this shows the factor of 2.5 very clearly. |
||
| − | |||
| − | In order to find out what's better, characters should first find out their personal time spent inside the FSR, e.g using an addon like [http://www.curse-gaming.com/en/wow/addons-1217-muse.html Muse] or RegenFu. It's important to perform the measurement under realistic conditions - the time spent inside the FSR while grinding is typically much lower than during a boss fight. Some players actually argue that in a tight situation, it's safe to assume that the FSR is in effect 100% of the time. It is possible to calculate the percentage of time which has to be spent outside the 5 second rule so that 2.5 points of spirit are more effective than 1 point of mp5. Examples: |
||
| − | |||
| − | Average lvl 70 priest with maxed [[Meditation]]: |
||
| − | 2.5 spirit return 2.5 mp5 outside the FSR, and 0.75 mp5 inside. The mathematical form of the question is thus |
||
| − | 2.5 * x + 0.75 * (1 - x) = 1 |
||
| − | 1.75 * x = 0.25 |
||
| − | x = 0.14 |
||
| − | |||
| − | So if that priest spends 14% percent of the time outside the FSR, the enchant with 15 spirit yields a higher regeneration than 6 mp5. If the time inside the rule is 86% or more, 6 mp5 is more efficient. |
||
| − | |||
| − | For lvl 70 characters without spirit regeneration inside the FSR: |
||
| − | 2.5 * x = 1 |
||
| − | x = 0.4 |
||
| − | |||
| − | That is they have to spend 40% of their time outside the rule for spirit to be better than mp5. |
||
| − | |||
| − | ====MP5 vs Intellect and Spirit - Formulas==== |
||
| − | The following formulas relate intellect, spirit, and mp5 to mana regen both in and out of FSR in an attempt to help establish a relative value between them depending on your current stats. |
||
| − | |||
| − | Based on the formulas for spirit-based regeneration above... |
||
| − | ManaRegen(Int,Spirit,MP5) = [0.001 + sqrt(Int) * Spirit * 0.005575] * 5 + MP5 |
||
| − | ManaRegenCasting(Int,Spirit,MP5) = [0.001 + sqrt(Int) * Spirit * 0.005575] * 5 * Coeff + MP5 |
||
| − | where Coeff is the decimal percentage of spirit-based mana regeneration that is allowed to continue while casting |
||
| − | |||
| − | The mana regen benefit per 1 point increase of Spirit, Intellect, or Mana/5 can be calculated as... |
||
| − | While not casting: |
||
| − | NC_RegenPerInt = 0.027875 * Spirit * [sqrt(Int+1) - sqrt(Int)] |
||
| − | NC_RegenPerSpirit = 0.027875 * sqrt(Int) |
||
| − | NC_RegenPerMP5 = 1 |
||
| − | |||
| − | While casting: |
||
| − | C_RegenPerInt = Coeff * NC_RegenPerInt |
||
| − | C_RegenPerSpirit = Coeff * NC_RegenPerSpirit |
||
| − | C_RegenPerMP5 = 1 |
||
| − | |||
| − | As you can see, MP5 is the only stat whose effect remains constant both in and out of casting. If you have no talents allowing mana to regenerate from spirit while casting, MP5 is the only way to do so. Even with them, MP5 is still quite valuable, given the most common of these effects (listed [[Mana_regeneration#Five_Second_Rule|above]]) cap at 30% spirit-based regeneration. |

Description
Aw man, this ain't good. Not one bit, mon.
Thrall's off to sea, Vol'jin's taking care of business in Echo Isles, and old Master Gadrin is left behind to take care of Sen'jin. And then what happens? Those humans come outta Northwatch Hold and set up camp in our backyard!
Lucky for us, they just got here, and they're still setting up their base. You can help out old Gadrin by destroying those big supply crates they carry, and by killing the laborers carryin' them. You'll find'm to the southwest.

Well, we've stymied their efforts for now, but they're still here. We'll have to press on, <name>.
Notes
In Northwatch Foothold.
The Northwatch Supply Crates start out around [52.6, 81.7] or so, and the Northwatch Lugs spawn at regular intervals. If left unmolested, they will form a chain of mobs between the spawn point and the encampments in Northwatch Foothold; however, if many players are killing them, they may be backed up, in which case simply wait at the spawn point on the shore.
The Lugs have a ridiculously small health pool (21 health) and are no challenge despite coming three to a crate. Be sure to strike them rather than having an ability like the druid's 
[Thorns] or hunter's pet kill them, as you will not receive credit.
