Oracle, UMD, and Ring of Revelation

[Momar]

If you have an oracle using UMD to emulate a mystery other than what the oracle actually has in order to use a ring of revelation, what is the oracle's effective level for using the revelation granted by the ring?

As I see it there are three options:
1) The oracle's level for the purpose of the revelation is UMD-20
2) The oracle is considered level 0 for the revelation
3) The oracle uses their normal oracle level for the ring's revelation

Mostly what's unclear to me is what is meant in the UMD emulate a class feature text regarding gaining an effective class level, and how far that extends into the use of the item.

UMD emulates the class and level only with respect to the magic item. All the magic item does is give you a revelation. The revelation, separately, looks at your actual oracle level for determining its effects. So option 3.

Alright. Thanks to both of you for responding.
