Zealot’s Oath - Path of Exile

Zealot’s Oath is a keystone passive skill. It applies life regeneration to energy shield instead of life. Just like Ghost Reaver making the ES leech rate based on max ES instead of max life, % life regen becomes % ES regen, and based on max Energy Shield.

Zealot's Oath Effect

As shown in the above example, the life is 1 and the energy shield is 12,011.

Percentage based life regeneration becomes percentage based ES regeneration based on maximum ES. Percentage based life regeneration can be gained from several unique items and passive skills.

Zealot’s Oath Build

  1. Life Regeneration. If you have life regeneration of 10% per second, this is applied to Energy Shield, meaning you now have Energy Shield regeneration of 10% per second.
  2. Anything which says it’s life regeneration will work with Zealot’s Oath.
  3. Life Flasks are not regeneration, and not affected. Note that life leech, among other things are not regneration.
  4. Chaos Inoculation(Maximum Life becomes 1, Immune to Chaos Damage). This works fine with Chaos Inoculation. If you have only 1 life, but 10% life regeneration, it turns into 10% Energy Shield regeneration.
  5. Vaal Pact(grants doubled life leech speed and maximum life leech rate, but causes life regeneration to have no effect). You won’t regen ES if you have Vaal Pact and Zealot’s Oath.
  6. Eldritch Battery(Energy Shield protects Mana instead of Life). If the character also has Eldritch Battery, life regeneration will apply to ES.
  7. Vitality(grants life regeneration to the caster and their allies). After getting Zealot’s Oath, life regeneration becomes based on your %shield. With the passive tree and level 20 vitality you can reach like 7.7% regen. 10000 energy shield + zealot’s oath = 770 ES regen per second = unkillable.
