Neverwinter Nights 2 Feats Database: Feat Details
Harper Spellcasting (Druid)
Feat ID: 1577
Type of Feat: Class
Use: Automatic
Prerequisite: Harper Agent
Installation: Neverwinter Nights (Base)

When a Harper agent gains an even-numbered level, he gains new spells per day (and spells known, if applicable) as if he had also gained a level in a spellcasting class he belonged to before adding the prestige class. He does not, however, gain any other benefit a character of that class would have gained (hit points, bonus feats, etc.), except for an increased level of effective spellcasting level. This spellcasting class is chosen from any spellcasting classes you have when you first become a Harper agent, and all Harper agent levels only improve spells per day progression in that one class.
