Eldritch knight

Although Obsidian has not confirmed it, the Eldritch Knight prestige class appeared to be in Obsidian's presentation at A-Kon.

DnD 3.5 Arcane trickster
Description: Studying the martial and arcane arts to equal degree, the Eldritch Knight is a versatile combatant who can cast fireball on her foes or charge them with sword drawn. The Eldritch Knight takes pride in her ability to use the right technique for the job: spells against physically tough foes and force of arms against spellcasting enemies.

Requirements

 * Feats: Weapon proficiency (martial)
 * Spells: Able to cast 3rd-level arcane spells

Bonus Feat
At the first level, an Eldritch Knight can select a bonus feat that would normally be available to Fighter (along with any from level advancement). The character must still meet any prerequisites for these bonus feats, including levels of fighter for the Weapon Specialization, Greater Weapon Focus, and Greater Weapon Specialization feats.

Spells per Day
From 2nd level on, when a new eldritch knight level is gained, the character gains new spells per day as if she had also gained a level in whatever arcane spellcasting class she belonged to before she added the prestige class. She does not, however, gain any other benefit a character of that class would have gained. This essentially means that she adds the level of eldritch knight 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 she became an eldritch knight, she must decide to which class she adds each level of eldritch knight for the purpose of determining spells per day.
