Weapon and Armor Proficiency: As the standard bard in the Player's Handbook. A prestige bard can cast any arcane spells in light armor without the normal arcane spell failure chance.

Spellcasting: When a new prestige bard level is gained (except at 1st, 3rd, 7th, and 13th level), the character gains new spells per day (and spells known, if applicable) as if she had also gained a level in whatever arcane spellcasting class she belonged to before she added the prestige class.

A prestige bard casts arcane spells from the schools of divination, enchantment, and illusion at +2 caster level. She casts arcane spells from the schools of evocation and necromancy at —2 caster level.

Bardic Knowledge (Ex): As the standard bard ability of the same name.

Bardic Music: As the standard bard ability of the same name, except that the minimum number of ranks in Perform required is increased by 5 (8 ranks for countersong, fascinate, or inspire courage; 11 ranks for inspire competence, and so forth).
