OK...the Arcane Bond a wizard has with an item...I get that I can cast one spell from my spellbook with it a day. I also get that it auto repairs when I prepare my spells.
The "add enchantments and abilities" thing is what gets me.
Quote:
A wizard can add additional magic abilities to his bonded object as if he has the required item creation feats and if he meets the level prerequisites of the feat. For example, a wizard with a bonded dagger must be at least 5th level to add magic abilities to the dagger (see the Craft Magic Arms and Armor feat in Feats). If the bonded object is a wand, it loses its wand abilities when its last charge is consumed, but it is not destroyed and it retains all of its bonded object properties and can be used to craft a new wand. The magic properties of a bonded object, including any magic abilities added to the object, only function for the wizard who owns it. If a bonded object's owner dies, or the item is replaced, the object reverts to being an ordinary masterwork item of the appropriate type.
Craft Wondrous Items requires Caster Level 3...if I add "Protective Penumbra" as the special ability to my bonded amulet, does it cost me anything? And what would it take to add other abilities to it?
