A low bellowing, groaning sound echoes through the cave, and a terrifying voice follows.

Thief in the shadows! My armour is like tenfold shields, my teeth are swords, my claws spears, the shock of my tail a thunderbolt, my wings a hurricane, and my breath death!

The stink of dragon in the air amplifies a hundred fold. His breath is even worse than death. But, instead of continuing to taunt you, the massive dragon lets out a pained groan as he falls onto his belly. His guts gurgle against the cave floor.

Ohhh... This gas is searing me on the inside! Little thief... If you can help relieve me of this terrible flatulence, perhaps I'll overlook your trespassing just this once...
