That staff that casts two spells per day, since I have to memorize spells do I just treat it like two extra slots and pick two spells per day to add to it? or does it spontaneously cast any spell I can cast at will without a need to pick ahead of time?<br/><br/>Also the instant cure moderate spells, it says 5/5, is that per day or is that 5 castings period ever?
