Land linnorms are wingless dragons. They have a strong dislike for humanoids, primarily because they gather the treasure that the land linnorms covet; they have been known to capture humans and humanoids, often using their magic, and force them to reveal the whereabouts of treasure hordes. They are solitary creatures, coming together only to mate and separating after the young pass the wyrmling stage. They will occasionally join forces to take down a very powerful foe, but will immediately split up again after the spoils are divided.
As wyrmlings, land linnorms have small green scales that glisten like gemstones. As they age, their scales grow, lose their luster, and begin to change color at the linnorms whim, changing from green to brown to gray. They have thin, hair-like spinal ridges and drooping ears.
Land linnorms live in hilly terrain near human settlements, usually lairing in caves, often one that they carved themselves using their stone shape ability. They can eat anything, including rock, but prefer flesh.
Land linnorms are usually cautious and will size up their opponents before taking them on, sometimes following them for days, often in human or animal form. They will only use physical attacks if they feel certain of victory, and they will abandon targets that appear too difficult.
Breath Weapon (Su): Land linnorms have a single breath weapon that has a duel effect. The weapon is a cone of searing heat. The heat also fatigues the victim severely; even if the targets save is successful, the blast deals 1d8 temporary Strength damage.
Spell-like Abilities: 3/dayinvisibility, dig, polymorph self, stone shape, conjure earth elemental, and earthquake. 1/daytransmute rock to mud and transmute mud to rock.
