How can you intentionally create a cursed object?
I would say the same way you would make an intentional non-cursed object. There are not rules for it since they are normally made by accident, but if a player wanted to make a cursed object I would say he could.
If the object was not one that is already in the book I might have to come up with some requirements though.
Cursed items happen when you botch your roll. I see no reason you couldn't botch it on purpose.
The problem is that the curse is usually random. If you want to make a specific cursed item, or an item with a specific curse, you'd be going into DM-call territory.
Were I your DM, I'd let you decide the curse (within reason) if you add 5 to the normal DC to make the thing.
You make an item using the spell "bestow curse."
You make an item using the spell "bestow curse."
Where is that rule located?
Cursed Items talks about random and specific cursed items. You can make a specific cursed item like any other item. As for making the random cursed item, ask your GM to be allowed to take 1 on your spellcraft check, thus intentionally failing badly enough to get a cursed item.
