Out of Arduin
A dragon-like demon
Pugnax is a demon, which appears as a 12-meter six-eyed red dragon with an additional gigantic clawed arm sprouting from the back of his neck. His visage inspires overwhelming fear (Will check at -4 or roll on fear table) and he turns all plant life nearby into ash. He is extremely resilient to damage and heals most wounds nearly instantly, but is particularly susceptible to blessed artifacts or holy water.
Pugnax was released from a Demon Whistle by Zat Damnrot when he was idly testing it to see what it would do. He was later found to be wandering the countryside near Natinuka and destroying much of the local forests. The party confronted and defeated him, chiefly through the use of several gallons of holy water.
