Energy shield

"Energy Shield" redirects here. For the basic passive skill, see Energy Shield (passive skill).

Energy shield is a form of defence that acts as an additional hit point pool on top of life.

Mechanics

Damage mitigation

If the character has any energy shield remaining when damage is taken, that damage is inflicted on energy shield first. Damage is only applied to life once all energy shield is depleted. The exception to this is chaos damage, which ignores energy shield.

Recharging

Effect of increased cooldown recovery on delay period

Energy shield will automatically begin to recharge if the character does not take any damage for a certain period of time. With Blood Magic, spending life instead of mana to use a skill counts as taking damage. By default, the delay period for energy shield to begin to recharge is 6 seconds. This can be reduced with Increased Energy Shield Cooldown Recovery modifiers from passive skills and equipment.

Let r be the sum of increased cooldown recovery modifiers. The delay period in seconds is given by:

600 / (100 + r)

For example, having 100% increased cooldown recovery results in a delay period of 3 seconds. Increasing cooldown recovery has sharply diminishing returns and the delay period cannot be eliminated entirely.

By default, energy shield recharges at a rate equal to a third of the character's maximum energy shield per second. Energy shield will stop recharging when it reaches maximum or if the character takes damage.

Stun avoidance

While the character has any energy shield remaining, it grants an additional 50% chance to avoid being stunned.

Skills

The Discipline aura increases energy shield of the character and nearby allies.

Passives

There are passive skill nodes that grant additional energy shield or a combination of bonuses including energy shield. Other passives such as Energy Shield Delay decrease the cooldown delay for energy shield to be restored after taking damage.
