'''Lava Plume (Su):''' As a standard action, you may cause a minor eruption from any fixed horizontal surface within 10 feet. This eruption originates from a 5 ft. square and plumes to a height of 10 ft. before receding, causing 6d6 fire damage to any creature occupying the square. For the next 1d4 rounds, creatures moving through that square take 1d6 fire damage from residual magma and convection.

'''Ash Cloud (Su):''' Once per encounter as a standard action, you may exhale a cone of hot ash or billowing smoke. The hot ash cone is 20 ft. long and provides total concealment for 1 round. At least one square of the ash cloud must share a border with your current square. Creatures within the cone take 12d6 fire damage, and may make a Reflex save (DC 10 + 1/2 HD + Con modifier) for half damage. The billowing smoke cone is 40 ft. long and provides total concealment for 2d4+Con modifier rounds. Creatures within the cone take 6d4 damage from the suffocating ash, and may make a Fortitude save (DC 10 + 1/2 HD + Con modifier) for half damage.

'''Eruption (Su):''' Once per day, you may unleash a massive eruption from any fixed horizontal surface within 200 feet. This eruption takes the form of a cylinder of lava 30 ft. in diameter and 60 ft. in height, dealing 2d6 fire damage per class level. Creatures within 60 ft. of the cylinder's origin take 10d6 fire damage from convection, but may make a Reflex save (DC 10 + 1/2 HD + Con modifier) for half damage. For the next 2d6 rounds, creatures moving through that square take 1d6 fire damage from residual magma and convection. Causing an eruption prevents you from using your lava plume or ash cloud abilities for 1d6 rounds.

'''Caldera (Su):''' You acquire the Fire subtype while this bond is active. Any physical attack that deals 10 or more damage to you results in a spurt of magma flying from the wound towards your attacker. If the attacker is within 5 ft. of you, he is automatically hit for 2d8 fire damage. You must display Volcano's sign to use this ability.

'''Nature's Sign (Su):''' Your skin becomes dark, brittle and rocky. Every step you take leaves a smoldering, incandescent footstep, making you extremely easy to track. Creatures within 5 ft. of you suffer 1d6 fire damage each round from the intense heat roiling within you, and flammable objects on your person or touched by you ignite. Metal you touch is affected as by ''heat metal.'' You exhale smoke, cough up cooling lava, and when enraged you begin smoking at the mouth and glowing red. You are now quicker to anger, and hard to calm when enraged.
