Vile Bastion

Vile Bastion is a notable Ascendancy passive skill for the Occultist. It grants bonus energy shield and energy shield regeneration for each enemy killed by you or your minions recently. It also grants immunity to stun while you have any amount of energy shield.

Since this passive grants energy shield regeneration, it is not removed by Vaal Pact, unlike life regeneration that is converted with Zealot's Oath.
