Reservation



Mana reservation is a method of using mana to pay for auras, herald skills, mine skills, or any skill with an ongoing effect. Rather than paying the mana cost once as with normal skills, a portion of mana is set aside as unusable for as long as the skill is active. Having mana reserved does not reduce the rate of mana regeneration, so it will reduce the time taken for mana to regenerate to its (temporary) maximum.

Reserved mana values are multiplied by support gem mana cost & reservation multipliers as usual. The Blood Magic passive will cause life to be reserved instead of mana.

Skills which reserve mana
Mana can be reserved in two ways:
 * By a fixed amount, which grows as the gem levels
 * By a percentage of maximum mana, which does not change with gem level



Reducing reservation
The amount reserved can be reduced by passives or items with the "" or "" properties. The amount reserved will NOT be reduced by the property "" such as from the gem. Flat mana cost reduction such as mod will not reduce reservation costs either.

The total of all "" modifiers whether from passives, jewels, or items, is summed before being applied. However "less" modifiers, and mana multipliers such as that granted by each apply as separate multiplications.

Jewels
A Jewel (either classic jewel, Abyss jewel, cluster jewel or Timeless Jewel) corrupted by a or Altar of Corruption can get  as an implicit modifier

Essences
The essence type Essence of Loathing can be used to guarantee a modifier (value depends of the tier of the essence) on helmets.

Passive skills
The passive skills with "reduced" reservation are all part of aura themed clusters.

There is a total of 14% reduction in the cluster in the outer Templar area, 12% in the cluster between Ranger and Shadow, and 4% each in the clusters in the Shadow, outer Duelist, and outer Scion areas. The Mortal Conviction keystone allows you to reserve one non-Banner aura for free, but prevents you from having more than one aura active.

Reservation calculations
The calculation to determine the reservation cost of an aura is: $\lceil \lceil \lfloor m \times M \rfloor \times (100% - l) \rceil \times (100% - r) \rceil$

Where $m$ = Base Mana Reserved, $M$ = Mana Multipler, $l$ = Less Mana Reserved, and $r$ = Reduced Mana Reserved.

The final percentage value is stored in 2 decimal place, while the actual reserved mana (life) value are rounded to the nearest integer.

With equipment and passives available as of version 2.3, each category includes the following.


 * Mana Multiplier: and corrupting a Body Armour with a  can give the item "" as an implicit.
 * Less Mana Reserved: Mortal Conviction.
 * Reduced Mana Reserved: All passive nodes which provide "reduced Mana Reserved",, , , and.

Examples of this calculation are as follows.

4% reduced Mana Reserved, and : $\lceil \lfloor 50% \rfloor \times (100%-4%) \rceil$ $\lceil 50% \times 96% \rceil$ $48.00%$

Mortal Conviction, 6% reduced Mana Reserved,, and : $\lceil \lceil \lfloor 50% \rfloor \times (100%-50%) \rceil \times (100%-(6%+25%)) \rceil$ $\lceil \lceil 50% \times 50% \rceil \times (100%-31%) \rceil$ $\lceil 25% \times 69% \rceil$ $17.25%$

Or, in the most extreme case, Mortal Conviction, 38% reduced Mana Reserved,, , , with  corrupted implicit, level 4 , and : $\lceil \lceil \lfloor 50% \times 84% \rfloor \times (100%-50%) \rceil \times (100%-(38%+8%+8%+25%)) \rceil$ $\lceil \lceil 42% \times 50% \rceil \times 21% \rceil$ $\lceil 21% \times 21% \rceil$ $4.41%$
