Cracked Orange Prism Ioun Stone: Casting 0th level spells from other spell lists?

[Arassuil]

I was wondering if the Cracked Orange Prism Ioun Stone lets one cast a cantrip/orison from a spell list that isn't his own?

Wearer adds one cantrip or orison (determined when the stone is created) to his list of spells known or spells prepared.

Price: 1,000 gp.

If the Ioun Stone had Prestidigitation, would that let a Cleric cast it, even though it's not on his spell list?

The wordings seems to imply that, even a non-caster would get access, it seems. This is also close enough to the usual pricing for such an item (0-level spell, unlimited uses) that this may be the intended effect.

p.s.: interesting name ;)

Ditto for your name. Does this mean you're the future of Pathfinder? ;-)

No, it doesn't allow non-casters to cast. A non-caster doesn't have a list of spells known or spells prepared to add to.

This does not give you the ability to cast spells. So I think the only requirement of the wearer is that they have a spell list (known or prepared). If you have a spell list then you add whatever spell is in the stone to that list and you may cast it as long as you wear the stone.

Answer to the OP question: YES
