Weapon and Armor Proficiency: Knights of the Blue Moon gain no proficiency with any weapons, armor, or shields. Selûne's favored weapon is the heavy mace, which Knights of the Blue Moon refer to as the moon's hand. Mystra's favored weapon is the shuriken, which Knights of the Blue Moon refer to as whirlstars.

Spellcasting: A Knight of the Blue Moon continues training in magic. When you gain a level in this class, you gain new spells per day and an increase in caster level (and spells known, if applicable) as if you had also gained a level in a spellcasting class you belonged to before adding the prestige class. You do not, however, gain any other benefit a character of that class would have gained. If you had more than one spellcasting class before becoming a Knight of the Blue Moon, you must decide to which class you add the new level for purposes of determining spells per day, caster level, and spells known.

Moon Blessing (Su): During days and nights of the waning or new moon, you can channel the influence of Selûne over the Weave to reduce the impact of magic directed at you. At the cost of a single attempt to turn undead, you receive a sacred bonus equal to +1 per class level on a single saving throw against a spell or spell-like ability. Using this ability is an immediate action.

During days and nights of the waxing or full moon, you can channel the influence of Selûne over the Weave to increase the impact of magic cast by you. At the cost of a single attempt to turn undead, you increase the saving throw DC of a single use of a spell or spell-like ability by an amount equal to your class level. Using this ability is a swift action.

Special Mount: At 1st level, you can call a special mount. This ability is identical to the paladin ability of the same name, except the mount will always match your alignment. Levels of paladin and Knight of the Blue Moon stack for purposes of determining the special mount's abilities. In addition, if you do not have a familiar, levels of sorcerer or wizard also stack for purposes of determining the special mount's abilities.

Faerie Fire (Sp): At 2nd level, you can use faerie fire, as the spell, three times per day.

Lunar Sight (Ex): Knights of the Blue Moon of 2nd level and above have low-light vision. If you already have low-lightvision, you instead gain improved low-light vision, which means that you see four times as far as a human in conditions of poor illumination.

Divine Moonlight (Su): At 3rd level, any spell with the light descriptor is heightened by one level, as if you had the Heighten Spell feat. The spell does not require a spell slot of higher level or require you to prepare such spells in advance.

Selûne's Foresight (Su): At 3rd level, you can tap into the prophetic powers associated with the moon, giving you a +2 insight bonus on initiative rolls.

Weavesight (Sp): At 4th level, you can use arcane sight, as the spell, three times per day.

Moon Kiss (Su): At 5th level, you can channel the silver light of Selûne into weapons or armor you use. When the moon is waxing or full, at the cost of a single attempt to turn undead, a magic weapon you wield receives the property of brilliant energy for 1 round. This use of the ability is a swift action.

When the moon is waning or new, at the cost of a single attempt to turn undead, armor you wear receives the property of spell resistance (SR 10 + character level) for 1 round. Using this ability is an immediate action.
