Elemental Type Armor Dissolve (Flame & Physical): When the weapon is fully charged, the next attack inflicts armor dissolve effect on the target for 45 seconds, increasing their flame and physical damage taken by 10% (and an additional 15% in team play).

Physical attacks will stun target under the dissolve effect for 2 seconds, and flame attacks will decrease the target's speed by 50% for 5 seconds. This effect can only trigger 1 time every 15 seconds on the same targets.  

Elemental Resonance Fusion of Mass and Flame: When the weapon deals damage, damage is calculated using the currently equipped weapon's highest physical/flame base ATK, the highest equipped physical/flame ATK percentage, and the highest equipped physical/flame damage boost, and the weapon is considered both a physical and flame weapon.

Can be triggered up to 1 time every 1.5 seconds. Central Nexus damage counts as normal attack damage. If any 1 frost or volt weapon is equipped, Central Nexus damage is multiplied by 1.3.
