Blessed of the Seven Sisters( Player's Guide to Faerûn, p. 176)
As a result of a personal connection to one of the Seven Sisters, you have a taste of Mystra's special favor.
Able to cast 6th-level arcane spells,
You may add the following spells to the spell list of one arcane spellcasting class that grants you access to 6th-level spells. 1st Level: Ray of hope, vision of heaven. 2nd Level Ease pain. 3rd Level: Blessed sight. 4th Level: Sword of conscience. 5th Level: Crown of flame, sacred guardian. 6th Level: Crown of brilliance. 7th Level: Righteous smite. If you have a spellbook, you may add these spells to your spellbook as normal. If you cast spells spontaneously in the manner of a sorcerer or bard, you may immediately, as an additional benefi t of this feat, swap any one spell that you know for a spell of the same level from the above list. After you take this feat, you may swap spells known according to the usual rules for your class.
