Energy Shield shown over mana, instead of life.

Eldritch Battery (often referred to as EB) is a keystone passive skill that makes energy shield protect mana instead of life.

Mechanics

Energy shield protects mana instead of life. All modifiers to energy shield apply normally but it is not affected by modifiers to mana or mana regeneration. Energy shield recharge and recovery through Zealot's Oath or Ghost Reaver function normally. Any reductions to mana (e.g. skill costs) will instead reduce energy shield by the same amount, and any reduction to energy shield will interrupt its recharging and reset its recharge delay.

With regards to skills like Blood Rage and Righteous Fire, Energy Shield is still counted in the degeneration applied to health.

Eldritch Battery also causes energy shields to no longer grant a chance to avoid stun.

Location

Eldritch Battery is a standalone keystone located on the upper right edge of the skill tree.
