What's the downside? Especially since it's only five levels.
Upon reaching levels 1, 3, 6, and 9 the character gains new spells per day as if he had also gained a level in his highest caster class (Paladin or Cleric). However, he does not gain increased duration, effects or power.
Yeah, I know I lost bardsongs/day, and I offset that with extra song feat. Bardsong effectiveness is still enhanced somewhat from what I saw.
an incredible plus in epic areas
Editing this for an information request; Acacea is a level twenty-seven bard. can you enlighten me/us as to the mechanics of bard past twenty? Do known spells increase? Are there additional spells available?
