Arcane Devotee

Spellcasting: Ability to cast 4th-level arcane spells.
Patron Deity: And arcane devotee must have a patron deity, and it must be the deity of which she is a devotee.

Weapon and Armor Proficiency: Arcane devotees gain no proficiency in any weapon or armor.

Spells per Day: An arcane devotee’s training focuses on arcane spells. Thus, when a new arcane devotee level is gained, the character gains new spells per day as if he had also gained a level in whatever arcane spellcasting class he belonged to before he added the prestige class. He does not, however, gain any other benefit a character of that class would have gained (bonus metamagic or feats, bard or assassin abilities, and so on). This essentially means that he adds the level of arcane devotee to the level of whatever other arcane spellcasting class the character has, then determines spells per day and caster level accordingly.

If a character had more than one arcane spellcasting class before he became and arcane devotee, he must decide which class he adds each level of arcane devotee for the purpose of determining spells per day.

Enlarge Spell: The arcane devotee may cast a spell as if it were under the effects of the Enlarge Spell feat. He does not need to prepare this spell in advance, and it does not increase the casting time or use a higher spell slot. This ability can be used a number of times per day equal to 1 + The arcane devotee’s Charisma bonus (minimum of once per day).

Sacred Defense: Add this value (+1 at 2nd level, +2 at 4th level) to the arcane devotee’s saving throws against divine spells, as well as the spell-like and supernatural abilities of outsiders.

Alignment Focus: A 2nd-level arcane devotee chooses one component of his deity’s alignment. He now casts spells of that alignment at a +1 caster level. If his deity is neutral, he chooses one component of his alignment for this focus. If the arcane devotee and his deity are neutral, the character chooses chaos, evil, good, or law for his focus.

Bonus Feat: At 3rd level, an arcane devotee can choose any one item creation feat or any feat from the following list: Spell focus, Greater Spell Focus, Spell Penetration, Greater Spell Penetration, Improved Counterspell, Magical Artisan, or Shadow Weave Magic (devotees of Shar only)

Divine Shroud (Su): Once per day, a 5th level arcane devotee may surround himself with a shroud of glowing divine power that protects him against enemy spells. The shroud is of a color appropriate to the arcane devotee’s patron’s alignment: constant blue for law, shimmering white for good, wavering black for evil, or flickering yellow for chaos. The shroud grants spell resistance of 12 + the character’s caster level as if he were under the effects of a spell resistance spell. This ability can be invoked as a free action and lasts a number of rounds equal to the arcane devotee’s Charisma bonus + 5.
