D&D: The Worth of Steel
"He spoke much of the magic – of lightning and enchantment – and gave exhibitions of power which sent his spectators away speechless."
Ugophaz has dominion over magic, fire, lightning, and all other forms of energy. It is chaotic and spontaneous, pure impulse and desire with little control or restraint. It seeks to overwhelm with it's boundless power, but has little consideration for what it's end goal is beyond "defeat enemies and win."
Ugophaz is also the breaker of barriers and the shatterer of oaths. In it's wake, marriages dissolve in an orgy of lust, and sworn vassals drop their duties to wander. It is brutal and hedonistic in turn, and like a lightning bolt seeks the path of least resistance.
It's easy to dismiss Ugophaz as a trickster god worshiped by rogues and sorcerers, but this is not the case. There is a difference between trickery to get ahead, and pure anarchy. Those who uphold Ugophaz seek to follow their impulses, bouncing from one whim to the next, with no bonds at all the hold them back, not even camaraderie, loyalty or blood.
