Linnorm, Tarn

CR 20.00 Dragon CE Colossal
This nightmarishly huge, snake-like dragon possesses two equally fearsome heads. Its twin jaws seethe with acid and poison.

Although legends speak of even more powerful linnorms, it's hard to believe after witnessing the devastation a two-headed tarn linnorm can wreak. Content to slumber away the centuries at the bottom of dark mountain lakes, the tarn linnorms are true horrors that even the mightiest of heroes fear.

A tarn linnorm is 120 feet long and weighs 24,000 pounds.

Breath Weapon — Once every 1d4 rounds as a standard action, a tarn linnorm can expel a 120-foot line or a 60-foot cone of acid, dealing 22d8 points of acid damage to all creatures struck (Reflex DC 32 halves). This acid creates toxic fumes when it consumes organic material—on the round after a creature takes acid damage from this attack, it must make a DC 32 Fortitude save or take 2d6 points of Strength damage from the poisonous fumes (this secondary effect is a poison effect). As a full-round action, the linnorm may breathe acid with one head and bite with the other (but not use its other weapons). Alternatively, as a full-round action, it can breathe acid from both heads to create two adjacent 60-foot-long cones or two separate 120-foot-long lines. In this case it cannot use its breath weapon again for 2d4 rounds. The save DC is Constitution-based.
