the identify spell: 1. costs 100gp to cast 2. must be learned 3. must be prepared 4. can be cast on a non magical item wasting 100gp 5. requires that you know which item is magical (usually obvious, you can also use detect magic) 6. some magical items are automatically identified when picked up and require no casting of identify a store identify: 1. you can identify as many items as you want in a row 2. costs 100gp 3. you cannot identify a non magic item 4. automatically tells you which item are "not identified" (aka, magical AND require a casting of identify)... is there a point to the spell? doing it in the store is just vastly superior... also, how come every merchant knows how to cast identify AND is performing the service at COST AND can cast it an infinite amount of times a day AND has detect magic at will? for hardcore PnP reproduction it should cost more, but people will likely complain, so maybe make the spell a little better? say, 50gp or even 90gp to cast the spell instead of 100gp? its more difficult and you have to jump through some hoops (detect magic then identify), but you can save a little cash doing it that way.
