Reservation

Reservation effects prevent a portion of a given resource — usually though it can also be Life or Mana — from being used for other purposes while active. Reserving a resource does not change the maximum value of that resource.

Reservation is a method of using a resource, typically spirit, to pay for a persistent effect, such as maintaining a permanent minion or buff.

Mechanics

When a resource is reserved, the reserved amount cannot be recovered, used to pay costs or as a defence, or otherwise provide its original function.

Reservation does not affect the maximum value of a resource, though it does affect the unreserved maximum value. A resource which is being reserved cannot be "full" (e.g. Full Life) unless the threshold is lowered below 100% of maximum resource (e.g. Idle HandsIdle Hands

+(5-10) to Intelligence

You count as on Full Mana while at 90% of maximum Mana or aboveThe devil finds work for idle hands.). Leech is removed by default once a resource is filled to its unreserved maximum; this is not the same as being at "Full Resource".

Persistent reservation effects do not deactivate on death.

Life Reservation

Example sources of life reservation can be found within the witch's Infernalist ascendancy.

Reservation efficiency

Reservation Efficiency is a modifier that affects the spirit reservation of spirit gems and some granted skills. All sources of #% increased/reduced Reservation Efficiency modifiers are summed before being applied to the calculation. It uses the following formula:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}{\text{Resource Reserved}}={\dfrac {\text{Base Reservation}}{1\ +{\dfrac {\text{Total Reservation Efficiency}}{100}}\ }}$

Example Reservations
Increased Reservation Efficiency	0%	25%	50%	75%	100%	150%	200%
30 Spirit	30	24	20	18	15	12	10
60 Spirit	60	48	40	35	30	24	20
100 Spirit	100	80	67	58	50	40	34

A reduced reservation efficiency of 100% or higher would cause skills to have infinite reservation, making the player unable to use any reservation skills.

Reservation Efficiency does not affect reservation effects that do not come from a skill, such as Widow's ReignWidow's Reign
