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

Reservation calculations
The calculation to determine the reservation cost of an aura is:
-
<math display="block" style="background-color:transparent; padding:0;"> \color[RGB]{163,141,109} \lceil \lceil \lfloor m \times M \rfloor \times (100% - l) \rceil \times (100% - r) \rceil </math>
(1)
Where <math display="" style="background-color:transparent; padding:0;"> \color[RGB]{163,141,109} m
</math> = Base Mana Reserved,
<math display="" style="background-color:transparent; padding:0;"> \color[RGB]{163,141,109} M
</math> = Mana Multipler,
<math display="" style="background-color:transparent; padding:0;"> \color[RGB]{163,141,109} l
</math> = Less Mana Reserved, and
<math display="" style="background-color:transparent; padding:0;"> \color[RGB]{163,141,109} r
</math> = 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.
