Vaal Pact

Vaal Pact is a keystone passive skill that grants doubled life leech speed and maximum life leech rate, but causes life regeneration to have no effect.

Mechanics

Interaction with Zealot's Oath

The Zealot's Oath keystone causes life regeneration to restore energy shield instead of life. Because Vaal Pact causes life regeneration to have no effect, taking it along with Zealot's Oath will prevent the character from regenerating energy shield. It will not prevent energy shield from recharging as it normally does. Note that energy shield regeneration, from sources such as Shavronne's RevelationShavronne's Revelation
Moonstone RingRequires Level 30+(15-25) to maximum Energy Shield+(60-75) to Intelligence

Right ring slot: Regenerate 6% of Energy Shield per second
Right ring slot: +250 to maximum Mana
Left ring slot: You cannot Recharge or Regenerate Energy Shield
Left ring slot: Regenerate 40 Mana per Second
Left ring slot: +250 to maximum Energy Shield"Shavronne held Sanity in her right
hand and Revelation in her left.
Brutus chose the left hand."
- Kadavrus, Surgeon to the Umbra, will still work, as it is specifically energy shield regeneration and not life regeneration converted by Zealot's Oath.
