Prerequisites:

Character must be 15th level or higher, A Sword Saint's "Focus" Class Feature, The "Roaring God's Style" feat, The "Aural Form: Resonating Fracture" feat.

Benefits:

Once per Focus as a Full-Attack Action, you make one strike at an enemy and this attack erupts with sonic damage. This attack's damage is equal to you melee strike's damage but its converted to sonic energy damage.

The range of this blast is 5Ft. per 10 damage you deal to the enemy with your weapon. The enemies affected may make a FORT save with a DC of 15 + 1 for every 10 damage dealt. Failing the FORT save will permanently deafen the enemy. Succeeding the FORT save will halve the sonic energy damage.

Example:

(You strike the enemy for 20 damage with your sword. The blast deals 20 sonic energy damage, has a blast radius of 10Ft. centered on you, and requires a FORT save of with a DC of 16 to halve the blast's damage and not be permanently Deafened).

Special:

You only take half damage and cannot become Deafened from your blast. If you succeed the FORT save you take no sonic energy damage.

Special:

This feat can only be used while in Focus and using the Roaring God's Style.
