Can I make an item identical to Eyes of Charming in every way, save that it uses "Charm Monster" instead?
It seems Very strange to me that Eyes of Charming uses a heightened Charm Person spell, instead of Charm Monster... and I can't seem to find any reasoning why a "Charm Monster" spell wouldn't work in its place.
Eyes of Charming
= 4 (heightened spell level) * 7 (CL) * 2000 (use-activated)
= 56,000 GP
Effect: On-use DC 16 Charm Person , CL 7th
New Item (Let's call it Eyes of Monster Charming)
= 4 (spell level) * 7 (CL) * 2000 (use-activated)
= 56,000 GP
Effect: On-use DC 16 Charm Monster , CL 7th
Edit: That Is right, isn't it? ... Raised to a 4th level spell, requires a minimum of 14 intelligence, +2 modifier, meaning a save DC of 10 + 4 + 2 = 16... It seems to fit the estimations perfectly. But the same calculations let you achieve an item with even greater use.... and one that lasts for Days, even, if successful.
Charm Monster is a very different spell than Charm Person. It is more restrictive in use and lasts much longer. However, you can certainly make an item to do it (pending your GM's approval).
How is it more restrictive, exactly? I would think that it would be in every way more useful...
Hmm, you're right. I must have been thinking of some other set of spells.
