Hmm that what i was thinking about:

Nocturnal stance: +5% Heal potency could work with a Piety/Det build for average shields (there is no effect that increase ur power of ur shields like Adlo from SCH thats why im thinking about not to use crit even if crit heal = ur shield)

Diurnal stance: +5% Attackspeed .. maybe a piety/SS build or SS/Det

sry for my bad english^^ german here
