Mana Reservation Efficiency Guide

Replace "Reservation Reduction" with "Reservation Efficiency". When stacked, Reservation Efficiency does not allow for infinite Auras. This can be given out much more liberally as a result, letting characters run additional Reservation Effects with only a couple of sources of Reservation Efficiency. The average character benefits, but the top end of extreme reservation has been made significantly weaker.

Modifiers to Reservation have been replaced with Reservation Efficiency. Reservation Efficiency works by dividing the cost of the Reservation Effect: 100% increased Reservation Efficiency would halve the cost of all Auras. 50% Reservation Efficiency cuts down costs enough to let you reserve an additional 50% Reservation Aura.

Passives and item modifiers with reduced Reservation have been replaced with increased Mana Reservation Efficiency, generally at double the value of the previous reduced Reservation value, but sometimes with different values for balance reasons. This means that a small amount of Reservation investment is more impactful than before, while high investment doesn’t allow as many Auras to be used. The vast majority of Reservation Efficiency offered is now Mana-specific in order to prevent reserving both Life and Mana being the default choice for a build heavily invested in Reservation. Generic Reservation Efficiency and Life Reservation Efficiency are still available on some item modifiers.

  • If not mentioned below, all sources that previously provided reduced reservation, including for specific skills or types of skills, now provide increased mana reservation efficiency at twice the value of the reduced reservation they used to give. Modifiers on existing items are affected by these changes.
  • Notable passive skills granted by cluster jewels that previously granted reduced reservation of a specific aura now grant 60% increased mana reservation efficiency of that skill for auras that have 50% base reservation, and 100% increased mana reservation efficiency of that skill for auras that have 35% base reservation.
  • The Hierophant’s Sanctuary of Thought Notable Passive Skill now provides 25% increased Mana Reservation Efficiency, instead of 10% less Mana Reservation.
  • Helmet enchantments that previously granted reduced reservation of a specific skill now grant the following values of increased mana reservation efficiency for that skill. Existing items will instead have twice the previous reduced reservation value (generally lower than the new values). Enchantments for skills that have 50% base reservation now grant 20/30% increased mana reservation efficiency, for Merciless and Eternal Labyrinth versions respectively. Enchantments for skills that have 35% base reservation now grant 30/45% increased mana reservation efficiency. Enchantments for skills that have 25% or flat base reservation now grant 50/75% increased mana reservation efficiency.
  • The Corrupted Implicit modifier on Jewels that previously provided 1% reduced Reservation now provides 2% increased Reservation Efficiency, not specific to mana.
  • Skyforth now grants 12% increased Reservation Efficiency (not specific to mana), instead of 6% reduced Reservation.
  • Hyrri’s Truth now grants “Precision has 100% increased Mana Reservation Efficiency”, instead of “Precision has 50% less Reservation”. This change applies to existing items.
  • Replica Hyrri’s Truth now grants “Hatred has 100% increased Mana Reservation Efficiency”, instead of “Hatred has 50% less Reservation”. This change applies to existing items.
  • Essence Worm now grants 80% reduced Reservation Efficiency (not specific to mana), instead of 40% increased Reservation.
  • Memory Vault now grants 20% reduced Reservation Efficiency (not specific to mana), instead of 10% increased Reservation.
  • Unique items that previously granted a specific skill 100% reduced reservation now cause that skill to have no reservation. This change applies to existing items.
  • Items that previously caused socketed gems to have reduced reservation have been balanced separately to other reservation efficiency effects. They still provide generic reservation efficiency rather than mana reservation efficiency, but generally have values lower than double the amount of reservation reduction they used to provide. Existing items will be updated to the functionality and values stated below, but will still display the old values unless updated with a Divine Orb.
  • The Shaper and Hunter Influence Shield modifiers that previously granted 10/15% reduced Reservation of Socketed Gems now grants 15/20% increased Reservation Efficiency of Socketed Gems.
  • The Synthesised Implicit modifier that previously granted 10% reduced Reservation of Socketed Gems now grants 20% increased Reservation Efficiency of Socketed Gems.
  • Prism Guardian now grants “Socketed Gems have 30% increased Reservation Efficiency”, instead of “Socketed Gems have 25% reduced Reservation”.
  • Victario’s Influence now grants “Socketed Gems have 45% increased Reservation Efficiency”, instead of “Socketed Gems have 30% reduced Reservation”.
  • The Devouring Diadem now grants “Socketed Gems have 25% increased Reservation Efficiency”, instead of “Socketed Gems have 20% reduced Reservation”.
  • Vivinsect now grants “Socketed Gems have 20% reduced Reservation Efficiency”, instead of “Socketed Gems have 10% increased Reservation”.
  • Heretic’s Veil now grants “Socketed Curse Gems have 20% increased Reservation Efficiency”, instead of “Socketed Curse Gems have 12% reduced Reservation”.
  • Rotblood Promise now grants “Socketed Curse Gems have 80% increased Reservation Efficiency”, instead of “Socketed Curse Gems have 50% reduced Reservation''.

Why introduce Reservation Efficiency?

Problem: The Reduced Reservation stat provides very little benefit at low values, but becomes very powerful when heavily invested in. This allows players to run every Aura in the game. It also forces Reduced Reservation to be balanced around extreme levels of investment, limiting how useful it can be to characters that do not run enormous numbers of Reservation Skills. Finally, characters that heavily invested in Reduced Reservation in order to run more skills on Mana were also able to reserve Life extremely effectively as well with no further investment, rendering this the only sensible way to play most heavily reservation-focused builds.

PoE 3.19 Changes

Problem: The introduction of reservation efficiency has encouraged a much larger range of builds to invest in reservation skills to a small or moderate degree. This is not a problem in itself, but currently the options for doing so are similar for every build, and provide slightly too much generic power relative to the investment required. Reservation mastery options are the biggest outliers in power, as they provide larger amounts of power than entire notable passive skills.

Solution: Remove the mana reservation efficiency mastery and reduce the power of the aura effect and life reservation efficiency masteries.
  • The Reservation Mastery that granted 15% increased Mana Reservation Efficiency of Skills has been removed from the Passive Skill Tree.
  • The Reservation Mastery that grants increased Life Reservation Efficiency of Skills now has a value of 20% (previously 30%).
  • The Reservation Mastery that causes Auras from your Skills to have an increased Effect on you now has a value of 10% (previously 15%).
