A small change to nw_s0_identify, the spell Identify:
If cast on a specific item then it will identify that item instead of granting a lore bonus.
Note: the inventory page needs to be refreshed or the item needs to be re-examined for it to lose the blue "unidentified" highlight, but the item is identified.
The ERF can be imported into a module, or the nss/ncs files can be unzipped to the override directory.
Just use GetIdentified() to check the identified flag instead of specific base items. You wouldn't want it to work on any item that is already identified. Non-magical items are considered identified.
