Actually... Magic Fang<em>would</em>be 500 XP, since Sam has one less rank there, but since Monk weapons are also treated as manufactured weapons, and Magic Weapon is a first-level Cleric spell, which Sam can cast himself/herself, imposing another -10 to the DC, I could use Magic Weapon instead of Magic Fang to eliminate the need for any sort of XP cost at all there.  So, 400XP for both.  Maybe even none at all, if metamagic can be applied (namely Transmitting Kiss) to make them cantrips.<br/><br/>On that note, can metamagic be applied to ritual spells?  Any and all ritual spells, or only ones I prepare and cast myself?  Would I be able to use metaphysical metamagic on these ritual spells to keep from increasing the DC were I to, say, empower a spell?  Or if I were to persist a spell, in order to skip straight to the days-to-permanent shift?  And if I take a spell from 4th-level to 3rd-level, does it become mortal circle?
