Vile Bastion

Vile Bastion

Ascendancy Notable Passive Skill

Regenerate 2% of Energy Shield per second for each
Enemy you or your Minions have Killed Recently, up to 10% per second
Cannot Be Stunned while you have Energy Shield
Regenerate 40 Energy Shield per second [1]

Vile Bastion is a notable Ascendancy passive skill for the Occultist. It grants flat energy shield regeneration and percentage 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. Hits that fully deplete energy shield will not stun the player.

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

Ruthless mode

Vile Bastion (Ruthless)

Ascendancy Notable Passive Skill

Damage taken Recouped as Life is also Recouped as Energy Shield

Vile Bastion in Ruthless mode does not grant energy shield regeneration or stun immunity while you have energy shield. Instead, it causes your life recoup to also apply to energy shield.
