Way of the Volcano

Practitioners of this fighting style are the masters of assault. Throwing flurries of attacks before an explosive dramatic finish.

Pressure Charge

Starting when you choose this tradition at 3rd level, you may choose to store your ki and allow it to simmer and gain pressure until it explodes with much more power. For each consecutive round that you choose to move one ki point to your Pressure Charge by spending an extra ki point after using ki abilities, the ki charge stored up in the Pressure Charge doubles. (At the end of round 1 the Pressure Charge will have 2 ki points; at the end of round 2 the Pressure Charge will have 6 ki points; at the end of round 3 it will have 14 points, and so on.) After 3 or more rounds, as an action you may choose to release the Pressure Charge, adding 1 point of force or fire damage to a successful attack against one opponent for every 2 ki points stored in the Pressure Charge.

Volcanic Mist

Beginning at 6th level, you may choose to expend ki points to create a cloud of fiery ash at a point of your choosing you can see. The spherical cloud will have a radius of 5 feet for each ki point spent and deal 1d10 fire damage to any enemy creature that begins its turn inside the cloud.

Pressure Wave

At 11th level, as an action you may use all ki points stored in the Pressure Charge to generate an explosive wave that affects all enemy creatures within a 15-foot radius sphere with you as the point of origin. All targets that fail a dexterity saving throw against your ki save DC take 1 point of force damage for every 2 points of ki stored in the Pressure Charge. Additionally, all enemy creatures that take damage from the wave are stunned and knocked prone until the end of their next turn.

Eruption

At 17th level, you have become a walking embodiment of the power of the volcano. You may expend ki points to use Pressure Charge, Volcanic Mist, and Pressure Wave simultaneously as an action. Use Pressure Charge and Pressure Wave together as an action. For each ki point dedicated to this dual attack, you add 2 points of force or fire damage to a successful attack on a single target and generate an explosive wave that affects all enemy creatures within a 15-foot radius sphere with you as the point of origin. All targets that fail your ki save DC take 1 point of force damage for every point of ki stored in the Pressure Charge. Use Volcanic Mist immediately. The spherical cloud has a radius of 5 feet for each ki point dedicated to Volcanic Mist and deals 1d10 fire damage to any enemy creatures that begin their turn inside the cloud.
