After using Concealed Heavy Wounds from the Five Way Imprint Inscription on his Sword of the Storm, Izroth managed to slow Smiling Demon down.
The active effect of Concealed Heavy Wounds made it so that those affected would have their total body mass increased by 200% for five seconds. However, the most useful thing about this effect was that it did not count as crowd control. This meant that even with the level difference between Izroth and Smiling Demon, the Siren Head Master could not merely shake it off.
Once Smiling Demon's speed was reduced and his balance thrown off from the sudden change in his mass, Izroth wasted no time activating his Light Feather Footwork and Flickering Steps in sync. In addition to the speed buff he received from Empyrean's Heaven Connecting Tether, Izroth soared through the sky at terrifying speeds.
