When surrounded or stun-locked (especially by Infested ), the jump attack is useful in inflicting persistent fire damage in a radius.
The Dual Heat Sword is the only melee weapon that has no polarity for its Stance slot, allowing it to use either Swirling Tiger or Crossing Snakes stances without penalty. For optimal modding however, it is recommended that Forma be used to polarize the slot to the desired polarity.
High Slash damage and Heat damage slam attack make it very effective against many types of Infested flesh and Cloned Flesh.
This weapon was released on February 8, 2013 with Update 6.2.
Jump attacks will make the Heat Sword emit a visible ring of fire upon slamming the ground. This visual trait is shared with other Heat weapons like the Heat Sword and Heat Dagger.
The Dual Heat Swords received a visual change in Update 16.5, giving it a faded color scheme with texture animations similar to those found in Prisma weapons.
