Some Minstrels use magic in order to aid their talents and skills, diversifying their reservoir because of this.
Spellcasting
You gain arcane spellcasting as a Mage of your level, gaining 1/2 Magic (minimum 1) in spells learned at 1st level. Every even level (starting at 2nd level), you receive a bonus spell known. Your MP is as per a Mage of your level as well.
This replaces Perform.
Illusion Damage
When casting a damage-dealing spell you can choose to make the spell target Mental Defense instead of Defense or Avoid. On a successful hit, the spell deals its damage and the target is confused for 1d5+1 rounds. On a failed hit the target takes no damage, and is immune to other Illusion Damage spells for the rest of the day.
This replaces Improved Perform.
My Friends and I
Spells with the Target of “Self” or “Self or Adjacent Ally” or “Adjacent Ally” instead always affect yourself, and a single adjacent ally of your choice.
This replaces Greater Perform.
Magical Courtesan
You gain a +8 bonus to all Defenses against magic (on top of the bonuses from Resistance), and have immunity to psychokinetic damage.
This replaces Unleashed Perform.
