  • Gain 30% of Maximum Mana as Extra Maximum Energy Shield
  • 10% less Mana Reservation

Sanctuary of Thought is a notable Ascendancy passive skill for the Hierophant that grants reduced mana cost, less mana reservation, and additional maximum energy shield equal to a percentage of the user's maximum mana. It also grants more reduced mana cost while the user is at full energy shield.


The extra energy shield granted by Sanctuary of Thought behaves like a conversion, and is therefore affected by both modifiers to mana and maximum energy shield.[1] With no "more" modifiers, the total additional energy shield granted is given by

 Additional Energy Shield = Base Mana * ( 0.30 ) * (1 + % increased maximum Mana + % increased maximum Energy Shield )

Modifiers like more maximum Energy Shield and more maximum Mana apply multiplicatively as usual.
