harpers get an extra spell - harpers call. like raise dead cept costs 10 hp - an be a lifesaver tho.

since jah is a harper she get that. i dont think she has any other extras. havent got round to a PC druid and dont like cernd so ic ant say for sure.

if you mean memorisable spells then it could be due to wisdom, which earns bonus spells above a certain level. or there are items which grant extra spells - like the ring of holiness if thats in BG2.
