Chosen of Mystra

Special Qualities: A Chosen of Mystra retains all of the special qualities of the character and also gains the following: Bonus Spells (Sp): The Chosen of Mystra may choose one spell, of each level one through nine, which she may use once per day as a spell-like ability. The caster level for these spells is equal to the Chosen’s character level or Hit dice; and saving throw DC’s are Charisma based. Once chosen, these spells cannot be changed.
Spell Immunity (Su): The Chosen of Mystra may choose one spell, of each level one through nine, which she is completely unaffected by as if protected by a Mystran Spellward spell (see New Spells below). Once chosen, these spells cannot be changed.
Weave Focus (Su): Upon gaining this template, a Chosen of Mystra is forever barred from ever taking the Shadow Weave Magic feat. In addition, all spells cast through the Weave by a Chosen of Mystra have a +5 bonus to their saving throw DC's and +5 to their effective caster level (for purposes of determining level dependent spell variables, Dispel Checks, Spell Resistance checks, and opposed caster level checks).
Immunities (Ex): A Chosen of Mystra is immune to Blindness, Deafness, Disease, Disintegration, Fatigue, Exhaustion, Poison, and Sleep effects.
Immortality (Ex): Chosen of Mystra are naturally immortal and cannot die from natural causes. Chosen do not age, and they do not need to eat, sleep, or breathe. The only way for a Chosen to die is through special circumstances, usually by being slain in magical or physical combat.
Detect Magic (Su): line of sight.
Mantle of Mysteries (Su): A Chosen is immune to all Scrying and divination effects, and all effects that discern her thoughts or alignment. Likewise, a Chosen cannot be controlled or compelled by any magical, supernatural, or psionic abilities or effects, although a clever chosen may play along and pretend to be acting under an enemy’s charm or compulsion. In addition, a Chosen's Truename cannot be discovered or discerned by any being unless the Chosen willingly chooses to reveal it to them.
Name and Song Attunement (Su): Whenever a Chosen’s name or the Rune of the Chosen is spoken, the Chosen hears it and the next nine words uttered by the being that spoke her name or recited the song. This ability does not inhibit or interfere with concentration, and can be suppressed or resumed as a free action.
Silver Fire (Su): All Chosen of Mystra can wield the Silver Fire (ability updated; see below).
Saves: +5 sacred bonus to all saving throws against spells and spell-like effects.
Abilities: +10 Constitution.
Skills: +10 insight bonus to Spellcraft checks.
Feats: Initiate of Mystra.
Spells: Same as the character, however a Chosen of Mystra with levels in any of the following spellcasting classes gains the following additional abilities:
Wizard: The Chosen may learn, scribe, and research new spells with much more ease than a normal Wizard. To study newly discovered spell or scribe a new spell into a spellbook only requires one hour instead of one day, and the material costs and time required to research new spells are halved
Sorcerer or Bard: once per day the Chosen may choose to remove a known spell from her known spell repertoire and replace it with a new spell of the same spell level from the appropriate class spell list. Removing a known spell in this fashion does not prevent a Chosen from relearning the same spell in the future.
Cleric: The Chosen may spontaneously cast any spell in the Spell, Magic, Illusion, Knowledge, Luck, or Good Domains and all Initiate of Mystra spells of any spell level that she can cast, using any cleric spell slot of the appropriate spell level.
Druid The Chosen gains access to all spells in the Spell, Magic, Illusion, Knowledge, Luck, or Good Domains and all Initiate of Mystra spells, and may prepare them in any druid spell slot of the appropriate spell level.
Paladin or Ranger The Chosen may select any two of Mystra’s domains, and may prepare and cast any spell upon those domain lists using any paladin or ranger spell slot of the appropriate spell level.
Unknown Powers: Many of the powers of a Chosen of Mystra may remain as of yet unrevealed, in some instances even to the Chosen themselves.
Level adjustment: +5.
