Changes

'''{{Anchor|Spells per Day/Spells Known}}:''' At each level after 1st, an Argent Battle Mage gains new spells per day (and spells known, if applicable) as if she had also gained a level in an arcane spellcasting class to which she belonged before adding the prestige class level. She does not, however, gain any other benefit a character of that class would have gained (such as the bonus feat sometimes gained by a wizard). If she had more than one arcane spellcasting class before becoming an Argent Battle Mage, she must decide to which class to add each level for the purpose of determining spells per day and spells known.

'''{{Anchor|Bonus Feat}}:''' At 3rd, 6th, and 20th level, an Arcane Battle Mage gains a bonus feat. At each such opportunity, she can choose a metamagic feat, an item creation feat, or Spell Mastery. The Arcane Battle Mage must still meet all prerequisites for a bonus feat, including caster level minimums.
