When you deal damage with the weapon, you can use a Free Action to make an Arcanite or Spell attack against the Fortitude DC of your target. On a Hit, your target loses a total number of charges on the Infusions affecting it equal to the Tier of this weapon (the charges lost are determined by the GM, and split as evenly as possible across the Infusions affecting the target). On a Critical Hit, the target also cannot use the Sustain action until the start of your next turn.
While wielding the weapon, you can spend 1 charge of either Mana Flux or Inspiration to gain a +4 Bonus to any skill check or attack roll you make to destroy a magic item or active magical effect, including the special attack roll granted by this enchantment.
