Order of the Spell
A cavalier who belongs to this order are more devoted in the practice of arcane magic than other orders, focusing on a particular school of magic, and engaging in spellcasting for the pure joy of it. Cavaliers of this order tend to be focused, driven, and unyielding in their search for new and grander spells. This order complements the Aegis Lancer multiclass archetype.
Edicts: The cavalier must select a single arcane school (see Arcane Schools entry of the Wizard class in the Core Rulebook). He must then seek to master the magic within his grasp, and strive to enhance or improve it. He must always place the purity and love of magic above all other things. The cavalier must take every opportunity to ensure those seeking to further magic in all its facets are given the opportunity to so, so long as it is not detrimental to magic itself.
Challenge: Whenever an order of the spell cavalier issues a challenge, he receives a +1 morale bonus on the caster level of any spell or spell-like ability (including aegis Arcanum) used against the target of his challenge. This bonus increases to +2 at 9th level, and +3 at 17th level. Furthermore, should the spell cavalier confirm a critical hit against the target of his challenge that has spell resistance, the target must make a Will save against a DC equal to 10 + 1/2 the cavaliers level + his Intelligence modifier or have his spell resistance reduced by 2 until the end of the challenge. At 12th level, the target’s spell resistance is reduced by 4.
Skills: An order of the spell cavalier adds Knowledge (arcana) (Int) and Spellcraft (Int) to his list of class skills. In addition, beginning at 6th level, an order of the spell cavalier gains a +1 bonus to the save DC of a single spell or spell-like ability he possesses (including aegis arcanum) once per day, and an additional time per day every six levels thereafter.
