Arcane Bond Questions

[Mir]

Going over arcane bond I seem to have the way I think it works and then upon poking around I find statements pointing to other interpretations (some of these may be out of date).

1. Would 3rd lv wizard/4 level prestige class that has raised is arcane caster level to 7 be able to add abilities to their bonded ring?

"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)."

The character would be a wizard and would meet the feat prerequisites which is all that is indicated is required. The next sentence gives an example of the 5th lv is an example of a wizard that has done this it does not say the character must be a wizard.

From this I assume there is no problem for the character that has taken the prestige class to add abilities.

2. Can a ring of protection be turned into a ring of protection/invisibility/whatever? I saw a statement from someone saying this was not possible but the rules text says "add" and the magic item rules indicate this is possible (though at increased cost).

"If the item is one that occupies a specific place on a character's body, the cost of adding any additional ability to that item increases by 50%. For example, if a character adds the power to confer invisibility to her ring of protection +2, the cost of adding this ability is the same as for creating a ring of invisibility multiplied by 1.5."

1) The level requirement for Forge Ring is Caster level 7th. You satisfy that requirement so, yes you can do that.

2) Yes.
The sentence right above the one you quoted:
"The cost to add additional abilities to an item is the same as if the item was not magical, less the value of the original item. Thus, a +1 longsword can be made into a +2 vorpal longsword, with the cost to create it being equal to that of a +2 vorpal sword minus the cost of a +1 longsword."

So yes, you can add new properties to an already magic item. That they used a weapon as example here doesn't matter.

Thanks, I kept running into statements going contrary to my understanding and thought it a good idea to double check.

Specific > General

Rules overlap each other, in this order, by design.
