Although small for a tarn linnorm, he is still rather enormous—if he notices anyone approaching his nest, he bursts from the still waters of the lake to roar a challenge and then attacks. He fights to the death.

Once every 1d4 rounds as a standard action, he can expel a 120-foot line or a 60-foot cone of acid, dealing 18d8 points of acid damage to all creatures struck (Reflex DC 28 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 28 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, he may breathe acid with one head and bite with the other (but not use its other weapons). Alternatively, as a full-round action, he can breathe acid from both heads to create two adjacent 60-foot-long cones or two separate 120-foot-long lines. In this case he cannot use its breath weapon again for 2d4 rounds. The save DC is Constitution-based.
When a creature slays him, the slayer is affected by the curse of death.
He is under the constant effect of freedom of movement, as the spell of the same name. This effect cannot be dispelled.
He has true seeing, as the spell of the same name. This effect cannot be dispelled.
