Energy shield



Energy shield is a form of defence that acts as an additional hit point pool on top of life. Along with armour and evasion, energy shield is one of the three defence types that can implicitly appear on equipment. Unlike life, energy shield will recharge naturally after the character has not taken any damage for 2 seconds.

Every class starts with no energy shield, and gains 2% increased maximum energy shield every 10 intelligence.

Damage mitigation
If the character has any energy shield remaining when damage is taken, even damage from Labyrinth traps, that damage is inflicted on energy shield first. Physical damage reductions and elemental resistances applies to damage before it is deducted from energy shield. Damage is only applied to life or mana once all energy shield is depleted. The exception to this is chaos damage, which bypasses energy shield. ,, (during flask effect), and  (while not on Low Life or Low Mana) prevents chaos damage from bypassing the character's energy shield. causes 50% of chaos damage to not bypass energy shield, but causes 50% of physical damage to bypass it.

Start of Energy shield Recharge
Energy shield will automatically begin to recharge if the character does not take any damage for a certain period of time. Spending energy shield with Blood Magic, Eldritch Battery or sacrifice mechanic (for life this mechanic can be found on, for example, Rathpith Globe or Dark Pact) does not count as taking damage. By default, the delay period for energy shield to begin to recharge is 2 seconds. This can be reduced with modifiers from passive skills and equipment.

Let r be the sum of modifiers (as a percentage). The delay period in seconds is given by:

$\text{Delay Period} = {200 \over 100 + r}$

For example, having 100% faster start of Energy Shield Recharge results in a delay period of 1 second.

Energy shield Recharge Rate
Energy shield recharge rate is a form of recovery and is by default:

Energy shield will stop recharging if the character takes damage. This recharge rate can be increased with modifiers.

Stun prevention
While the character has any energy shield remaining the character has a 50% chance to ignore being stunned. This bonus is not additive with other stun avoidance modifiers from passive skills and equipment; the chance to ignore stun granted by energy shield is rolled separately.

Ascendancy skills
The following Ascendancy class skills are related to energy shields:

Version history

 * Energy Shield Recharge is no longer interrupted by non-damage changes to your Life or Energy Shield, such as when you spend your Energy Shield on skills via Eldritch Battery.


 * Energy Shield as a defensive mechanic has undergone a review and, generally speaking, all sources of Energy Shield on items have been reduced by approximately 20%.
 * Elreon's crafted Increased Maximum Energy Shield mod can now only be crafted onto Amulets. The cost has been changed to 8 Chaos orbs (from 1 Exalted orb).
 * All local Energy Shield modifiers on items, as well as the base Energy Shield of items, have been reduced at higher levels. Very low-level items will see a slight increase or no change, scaling up to a 33% reduction at the highest tier of modifiers.
 * Because of Armour/Energy Shield and Evasion/Energy Shield equipment, we've had to apply this change to the local percentage modifiers on all other armour types as well. To compensate, all inherent values of base Armour and Evasion Rating on equipment are now greater at higher item levels.
 * The defences granted by all body armour has been increased at higher levels by 20%.
 * These changes will not apply to existing modifiers but will apply to existing base types. As a consequence, the Energy Shield values on many unique items have also been updated.
 * The following mods can now be crafted at Haku's Armourer's Bench: +27-34 to Maximum Energy Shield can be applied to all Armour Slots, +35-45 to Maximum Energy Shield can be applied to Body Armour, Shield and Helmet, +56-69 to Maximum Energy Shield can be applied to Body Armour and Shield.
 * Local Added Energy Shield modifiers have been rebalanced at all levels. Early mods grant more energy shield, dropping to 36%-45% less energy shield at the highest tier.


 * The mod can no longer spawn on shields.


 * Introduced to the game.
