Arcane Bond: At 1st level, wizards forge a powerful bond with an object or creature. This bond can take one of two forms: The first is a familiar, following the standard rules for such creatures (see Familiars) and the second is a bond with an object, using it to cast spells and enchanting it with even greater powers.Objects that are the subject of an arcane bond must fall into one of the following categories: amulet, ring, staff, wand, or weapon. These objects are always masterwork. If the object is an amulet or ring, it must be worn to have effect, while staves, wands, and weapons must be wielded. If a wizard attempts to cast a spell without his bonded object worn or in hand, he must make a Spellcraft check or lose the spell. The DC for this check is equal to 20 + the spell’s level.A bonded object can be used once per day to cast any one spell that the wizard knows and can cast, just as if the wizard had cast it. This spell cannot be modified by metamagic feats or other abilities. The bonded object cannot be used to cast spells from the wizard’s prohibited schools.A wizard can enchant his bonded object as if he had the required feats. If the bonded object is a wand, it loses its enchantment when its last charge is consumed, but it is not destroyed and it retains all of its bonded object properties. Bonded objects only function for their creator, including any magic abilities added to the object. This means that they cannot be sold.If a bonded object is damaged, it is restored to full hit points the next time the wizard prepares his spells. If the subject of an arcane bond is lost or destroyed, it can be replaced after 1 week’s time in a special ritual that costs 200 gp per wizard level. This ritual takes 8 hours to complete.
