Rovagug (The Rough Beast) Source Divine Mysteries pg. 90
Source Divine Mysteries pg. 90, 
Player Core pg. 38 2.0Rovagug has no single holy scripture. He has little use for one, for his sole commandment is to destroy, and his followers need no instruction in how to accomplish that. The figurative and literal monsters who worship Rovagug share their myths and legends in secret shrines and hidden caves, calling him the Rough Beast, the Imprisoned King, the Tide of Fangs, the Unmaker, and the Worldbreaker. They tell each other that each life they snuff out, each piece of art they destroy, each work of labor they bring tumbling down puts a crack in the prison that holds their god. Each of their little efforts of destruction adds up and will one day free him, setting him loose to bring about the end of all things.

disintegrateRovagug's imprisonment means he can almost never intercede on Golarion, but some places lead far enough into the earth that the god's profane influence can leak through. He is as likely to curse those who draw his attention as he is to reward them, though great enough acts of violence and destruction may earn his favor.
Source Divine Mysteries pg. 93Minor Boon: Your attack becomes more destructive. Once, one of your failed or successful attacks becomes a critical hit, and your weapon or unarmed attack gains the 
deadly d12 trait for this attack, replacing any deadly trait it already had. Rovagug typically grants this boon when the critical hit could destroy something precious or significant.
Moderate Boon: You can devour all. Your mouth grows into a horrible, circular, insectile maw of needle-like teeth. You gain a bite unarmed attack that deals 1d8 piercing damage. Additionally, you can stomach eating anything you can fit down your throat—even rocks or small objects. You gain a +4 status bonus to saves resulting from eating something, such as diseases, poisons, or other effects of the ingested object. This doesn’t allow you to digest magic items that would otherwise be difficult or impossible to destroy, such as cursed items or artifacts.
Major Boon: You can crack the surface of Golarion, accelerating the release of the Rough Beast. You gain the 
Quaking Stomp barbarian feat; you can use this feat even when not in rage.
Minor Curse: Whenever you are imprisoned, you thrash and shake as your mind fills with desperation. Any time you are 
restrained or otherwise imprisoned (such as being sent to jail), you are also 
clumsy 2 and 
stupefied 2.
Moderate Curse: Your destructive rage seeks to remain unbound. Any armor you wear automatically becomes broken. Other items in your possession occasionally become broken over time.
Major Curse: You are useful only as a beacon of destruction. You are permanently 
confused, rampaging against anything and everything in your sight, and you deal an additional 18 damage with your unarmed and weapon Strikes.
