Sometimes wizards and sorcerers forge mystical bonds with their mounts, usually the result of casting beneficial spells on their mount (Spider Climb, Haste, Bullís Strength, etc). This bond results in the mount gaining special magical abilities and the rider achieving a state of oneness with their chosen mount. The Arcane Cavalier also practices/hones his combat skills when riding.

Concentration: 8 ranks.
Knowledge (Arcana): 8 ranks.

Weapon and Armour proficiency: Arcane Cavaliers gain no additional proficiency in any weapon or armour.
Base Attack Bonus: As per Wizard/Sorcerer, effective levels stack.
Base Saves: As per Wizard/Sorcerer, effective levels stack.
Spells per Day: When a new Arcane Cavalier level is gained, the character gains new spells per day as if he had also gained a level in a spellcasting class he belonged to before adding a prestige class. He does not, however, gain any other benefit a character of that class would have gained except for an increased effective level of spellcasting.
Special Mount: The Arcane Cavalierís mount gains all the special benefits of being a paladinís mount, but uses the characterís overall level to determine the mountís special abilities. The mountís alignment becomes that of the Arcane Cavalier.
Mounted Caster: The Arcane Cavalier has achieved an arcane oneness with his mount. He can cast spells while his mount is moving without having to make a concentration check. The caster must still make a concentration check if trying to cast defensively in combat.
Cavalier Feat: The Arcane Cavalier gains a rider feat (Trample, Ride-By Attack, Mounted Archery or Spirited Charge).
Arcane Horselord: The Arcane Cavalier becomes a master of men as well as his mount. He gains followers as if he possessed the feat ďLeadershipĒ. If the Arcane Cavalier already possesses the Leadership feat add a +2 bonus to the characterís effective Leadership score.
