Divine Bond

Upon reaching 5th level, a paladin forms a divine bond with her god. This bond can take one of two forms. Once the form is chosen, it cannot be changed. The first type of bond allows a paladin to form a divine bond with her weapon. As a standard action, she can call upon the aid of a celestial spirit for 1 minute per paladin level. At 5th level, this spirit grants the weapon a +1 enhancement bonus. For every three levels beyond 5th, the weapon gains another +1 enhancement bonus, to a maximum of +6 at 20th level. These bonuses can be added to the weapon, stacking with existing weapon bonuses to a maximum of +5. Alternatively, they can be used to add any of the following weapon properties: axiomatic, brilliant energy, disruption, flaming, flaming burst, holy, keen, and speed. Adding these properties consumes an amount of bonus equal to the property's cost. These bonuses are added to any properties the weapon already has, but duplicate abilities don't stack. A paladin can use this ability once per day at 5th level, and one additional time per day for every four levels beyond 5th, to a total of four times per day at 17th level. The second type of bond allows a paladin to gain the service of an unusually intelligent, strong, and loyal steed to serve her in her crusade against evil. This mount is a heavy horse. This mount functions as a druid's animal companion, using the paladin's level as her effective druid level. At 11th level, the mount gains the celestial creature simple template. At 15th level, a paladin's mount gains spell resistance equal to the paladin's level + 11.
