This ability states that :"If you have abilities or class features that require rest before they can be regained, you can choose to regain them once per day by spending 1 hour in uninterrupted meditation". Now, I'm wondering if it means that you can also regain spells. "Clerics meditate or pray for their spells. Each cleric must choose a time when she must spend 1 hour each day in quiet contemplation or supplication to regain her daily allotment of spells." This means that because its not a class feature that requires rest can't be sustained by faith?
furthermore, even if a hierophant can with this path ability regain spells,according to the basic magic rules, can or can't be spells casted in the last 8 hours?
