A Caster can only spend a limited amount of this energy to cast spells on one turn.Erf-b1-p090 Juice replenishes to full at the start of new turn. It is possible that sleep aids a Caster in performing actual spells.Erf-b1-p084
Scrolls are a way to "store" juice for later use as casting scrolls do not seem to spend Caster's own juice.Erf-b1-p125, Erf-b1-p129 Casters create scrolls on their turn, for a significantly higher cost in juice than simply casting the same spell. Perhaps, like the Juice spent to replace Motion in Croakamancy spells, this extra juice is spent to put the spell in stasis.
