Oracle Monsters??

[Zahir ibn Mahmoud ibn Jothan]

Ok, so there are a number of creatures that explicitly cast spells as if they were sorcerers. My quick examples are dragons.

Faerie Dragons casts as a sorcerer 3. Other dragons cast as sorcerers per their individual caster levels.

Are there any creatures that do this same thing, except casting as oracles? If so, what are they?

It's not exactly what you're looking for, but the lamia matriarch will get you close. Specifically, this ability:

Bestiary 2 wrote:

Spells A lamia matriarch casts spells as a 6th-level sorcerer, and can cast spells from the cleric list as well as those normally available to a sorcerer. Cleric spells are considered arcane spells for a lamia matriarch.

Kirin, and some naga are similar.

EDIT: And we have a winner: Lammasu

Euryale or whatever it is from Bestiary 6 is CR 20 with 18th level oracle spells.

One of the types of True Dragon cast as Oracles, the Planar Dragons.
