Pyro Knight

You discovered how to enhance your martial prowess using the supernatural power of fire. This ancient practice of fire magic originated with Fornax, the god of the forge, blessing his four champions with fire from his personal forge. However, with the Great Severance, FireKnight's have become few and far between, as the distribution of his power and influence is extremely limited. You may have been given power by Fornax himself, granted the knowledge to awaken it yourself with the help of a previous wielder, or learned from ancient tomes of Fornax. In time, you have learned to bend the wildness of fire to your will, and in doing so becoming a FireKnight.

Minor Pyro Blessings

Starting at 3rd level, The spark of Fornax begins to show within you. You gain a permanent 1d8 fire damage made with a melee attack. Your melee attacks also burn nonmagical flammable objects that aren't being worn or carried. This bonus increased to 3d8 at level 15 in the fighter class.

Blazing Circlet

At 7th level, your inner fire has begun to show more intensity. As an action, you can engulf your weapon if fire and spin in a circle, dealing fire damage to all adjacent enemies. When struck, the targets must make a dexterity saving throw or take 4d8 fire damage plus your strength modifier, or half as much on a successful save. Your saving throw DC is 8 + your proficiency bonus + your strength modifier. This damage increases to 8d8 and ignores resistance and immunity to fire damage at level 15 in the fighter class.

Once you use this ability, you can't use it again until the end of a long rest.

Pyro Warrior Spirit

At 10th level, your inner fire spirit now protects you from outside sources of fire and turn it against your enemies. You gain resistance to fire damage and when you take fire damage, the dealer takes the same amount that you did.

Enhanced Pryo Blessings

By, 15th level, your blessings have been increased even further. Your melee weapon attacks now deal an extra 3d8 fire damage instead of 1d8. They can also burn magical objects that aren't flammable, even if they are being worn or carried. Your Blazing Circlet ability now deals 8d8 fire damage instead of 4d8 and it ignores resistance and immunity of fire damage when this damage is applied.

Exalted Fire

At 18th level, your inner spark has finally erupted into a glorious inferno within. You gain immunity to fire damage, and heal for the amount of damage you would have taken. In addition, you can call upon the exalted fire within to unleash a devastating attack to enemies in a line. Enemies in a 120 ft must make a dexterity saving throw or take 20d12 fire damage on a failed save, or have as much on a successful save. Your save DC is the same as Blazing Circlet's save DC. This attack also ignores resistance and immunity to fire damage.

Once you use this feature, you can't use for the next seven days.
