You engulf the weapons of all allied creatures within range in raging flames, empowering them with destructive fire aura. This effect also applies to ammunition and projectiles, such as arrows, bolts, and thrown weapons. While this Technique is active, affected weapons gain the Flaming Surge Critical Feature.

Flaming Surge
Critical Feature: If you roll 12 or more on a d20 during the attack check, the attack deals +1 Fire Damage. If you roll 18 or more on the d20 during the attack check, the flames erupt violently in all directions, dealing 1 Fire Damage to all enemies within 2 meters of the target.

A weapon that leaves the Technique’s range retains this effect until the end of its next round.
