1st edition arcane focus and UMD

[Braininthejar]

In 1st edition, a wizard can enchant his arcane focus to turn it into a wand that only works for him.

Can another character use UMD to "emulat class feature" in order to use it too?

I don't believe pathfinder allows you to do that. But supposing that is allowed yes UMD would allow you to bypass that restriction.

"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 Chapter 5). 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."

"Being the wizard bonded to this specific arcane focus" isn't a class feature. It is a feature of the character. I don't think you can emulate it with UMD.

A class feature is something that anyone sharing the class or in some cases archetype shares. For this to work you would have to emulate every aspect of the character. That mean you would need to emulate a nearly infinite list of things. You would need to start with the characters class, race and alignment, all their ability scores, every single class feature and just about everything on the character sheet. This would also include any physical and social aspects of the character.

The only way I can see for another character to use a wizards bonded item would be to use a wish. If you are using a wish you would not need to bother with UMD. Using a wish is probably going to be pointless, but it should work.

no

you even posted the answer in your first line, "only works for him".

Wizard class - bonded object:

... 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.

it only functions for the wizard who owns it
that statement prevents UMD from working even if the roll was high enough to do so.
In a similar manner a second wizard with a bonded object of the same type cannot use the first wizard's bonded object without first performing the bonding ritual(1 week +8hrs +200*CL gp) which turns his original bonded object into a mundane mw object.
At that point the second wizard could use UMD on his own new Bonded Object with resounding success but that would be both redundant and silly. He could also try with his old mw mundane bonded object but it has no magical properties.

The Game is just a Rule Based model/system written in conversational simple american english with a implicit understanding of DnD3.5 play practices and middle school math. It requires a GM to interpret those rules using his sensibilities. It is a Work of Art and so getting pedantic or oversampling/over-parsing RAW just leads to fallacies.

It's fair to say some of these easily misunderstood rules can lead to new interpretations and interesting Home Games. It is a Game. The d20 system is pretty resilient and can handle significant sillyness producing "Games For Fun" using the "Rule of Cool".

Think of the bonded object this way… the object itself is completely ordinary and lacks any magical properties of its own. The wizard has formed a mental bond to this object that allows them to use it as if it were a magic item. In truth the magic from a bonded object comes from the wizard directly. When in their possession it is indistinguishable from a magic item, but when removed from their possession the truth of how unremarkable the item truly is is revealed.

So someone trying to UMD a wizards bonded wand is like trying to UMD a random stick picked up off the ground… unless the bonded wand is a real wand that simply hasn’t ran out of charges yet…

Use Magic Device skill.
there's no "emulate having performed a bonding ritual" on the list.

Emulate a Class Feature:

Sometimes you need to use a class feature to activate a magic item. In this case, your effective level in the emulated class equals your Use Magic Device check result minus 20. This skill does not let you actually use the class feature of another class. It just lets you activate items as if you had that class feature. If the class whose feature you are emulating has an alignment requirement, you must meet it, either honestly or by emulating an appropriate alignment with a separate Use Magic Device check (see above).

The skill does not let you actually use the class feature of another class. In this case that would be considered "owning" or having performed the bonding ritual.

still, it is with a GM's Home Rule to allow this usage. Sadly it is any spell that you could cast and generally the UMD user cannot cast spells and does not have a spell list.
