I have an interesting question about the PRC spell system, and this concerns epic spell research. My character has the proper seeds learned (and then some) to actually research the spell, not to mention the gold and XP requirements. However, the epic spell tome's Use Unique Power effect only describes what the spell does; examining the tome, though, gives a rather vague clue as to what needs to be done: it states that I need to find the proper locale (and class-dependent, at that) in which to research the spell. What exactly might these locations be for the various spellcasting classes, and where?
