Weapon and Armor Proficiency: An arcane archer is proficient with all simple and martial weapons, light armor, medium armor, and shields.

Spells per Day: At the indicated levels, an arcane archer gains new spells per day as if she had also gained a level in an arcane spellcasting class she belonged to before adding the prestige class. She does not, however, gain other benefits a character of that class would have gained, except for additional spells per day, spells known (if she is a spontaneous spellcaster), and an increased effective level of spellcasting. If a character had more than one arcane spellcasting class before becoming an arcane archer, she must decide to which class she adds the new level for purposes of determining spells per day.

Enhance Arrow (Su): At 1st level, an arcane archer can channel arcane energy into the arrows she lets loose. She can sacrifice one of her arcane spells for the day (of 1st level or higher), and for that round, she gains a bonus on her attack rolls equal to the level of the spell sacrificed, as well as extra damage equal to 1d4 points x the level of the spell sacrificed. This is a free action, but the bonuses do not stack with itself.

Imbue Arrow (Sp): At 2nd level, an arcane archer gains the ability to place an area spell upon an arrow. When the arrow is fired, the spell's area is centered on where the arrow lands, even if the spell could normally be centered only on the caster. This ability allows the archer to use the bow's range rather than the spell's range. It takes a standard action to cast the spell and fire the arrow. The arrow must be fired in the round the spell is cast, or the spell is wasted.

Seeker Arrow (Sp): At 4th level, an arcane archer can launch an arrow at a target known to her within range, and the arrow travels to the target, even around corners. She must sacrifice one of her arcane spells for the day (of 2nd level or higher) to use this ability. Only an unavoidable obstacle or the limit of the arrow's range prevents the arrow's flight. This ability negates cover and concealment modifiers, but otherwise the attack is rolled normally. Using this ability is a standard action (and shooting the arrow is part of the action).

Phase Arrow (Sp): At 6th level, an arcane archer can launch an arrow at a target known to her within range, and the arrow travels to the target in a straight path, passing through any nonmagical barrier or wall in its way. (A wall of force stops the arrow.) She must sacrifice one of her arcane spells for the day (of 3rd level or higher) to use this ability.  This ability negates cover and concealment, and is resolved vs touch AC. Using this ability is a standard action (and shooting the arrow is part of the action).

Hail of Arrows (Sp): As a full round action, an arcane archer of 8th level or higher can fire an arrow at each and every target within range, to a maximum of one target for every arcane archer level she has. She must sacrifice one of her arcane spells for the day (of 4th level or higher) to use this ability. Each attack uses the archer's primary attack bonus, and each enemy may only be targeted by a single arrow.

Arrow of Death (Sp): At 10th level, an arcane archer can fire an arrow of death that forces the target, if damaged by the arrow's attack, to make a DC 20 Fortitude save or be slain immediately. She must sacrifice one of her arcane spells for the day (of 5th level or higher) to use this ability. Using this ability is a standard action (and shooting the arrow is part of the action).
