Changes

'''{{Anchor|Spellcasting}}:''' At each every level except first and eight, 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 arcane spellcasting class to which you belonged before adding the prestige class level. You do not, however, gain any other benefit a character of that class would have gained. If you had more than one arcane spellcasting class before becoming a knight specter, you must decide to which class to add each level for the purpose of determining spells per day, caster level, and spells known.

'''{{Anchor|Warrior Mage}} {{Ex}}:''' Knight Specter can cast even if their hands are full of swords and shields. A knight specter can still employ somatic components with items in her hand. This does not remove the need for somatic components, they still will be unable to cast if bound or not free to move their arms. Additionally knight specter can cast in light armor without incurring arcane spell failure.Additionally Your caster level increases by +2. This can't increase your caster level beyond your HD. However, even if you can't benefit from the full bonus immediately, if you later gain levels in a non-caster class you may be able to apply the rest of the bonus.
