Here's the basic question: For purposes of determining what is "once per day", does the magic of a pearl of power work when the spell is recalled or when the recalled spell is cast?
Here's the situation: My character was a low level prepared-spell caster who wouldn't have time to prepare spells the next morning. He had cast only one first level spell. He had an unused first level pearl of power. I told my GM that I wanted to use the pearl to recall the spell before the day ended so that my spells would be fully prepared for the next game day. My GM ruled that this wouldn't work and explained why (more detail on that below).
I found his interpretation of the RAW reasonable, but unconvincing. Obviously, his interpretation is the rule for his campaign (and I am happy with his interpretation as a player because it ultimately makes pearls more useful). I also, however, run my own Pathfinder campaign, and I would like to hear others' interpretation.
The operative text for pearls of power is:
Quote:
Once per day on command, a pearl of power enables the possessor to recall any one spell that she had prepared and then cast that day. The spell is then prepared again, just as if it had not been cast.
My interpretation is that my character invokes the pearl with a command word (which is a standard action). The magic of the pearl works on my character at that moment and causes my character to recall the lost spell. After the spell is recalled, my character again has it prepared, exactly the same as if it had not been cast. The magic of the pearl of power could then be used again to recall another spell the next game day.
My GM interprets the RAW differently. He explained that, in his view, the magic of the pearl works when the recalled spell is cast. He compared the pearl to the Magius Spell Recall class ability. The operative text for that ability is:
Quote:
With a swift action he can recall any single magus spell that he has already prepared and cast that day by expending a number of points from his arcane pool equal to the spell’s level (minimum 1). The spell is prepared again, just as if it had not been cast.
Under his interpretation, a caster uses the pearl to recall a spell, but then draws upon the magic of the pearl to power the spell when casting it rather than the caster's own magical reserves. Recalling a spell the day before would offer no advantage to my character because the magic of the pearl wouldn't actually be expended until the next day when the spell is cast. (The upside to his interpretation for me as a player is that he also sees the act of recall the spell as a swift action like Spell Recall or perhaps even part of the spellcasting action like a Runestone of Power.)
I'd appreciate hearing other players' and GMs' thoughts. Thank you.
