Izroth used the Sword Return part of his Second Sword Form: Returning Wave to redirect the first of Sage's squalls towards Roudin who was more focused on Sage's actions. This opened a small window of opportunity for Izroth and he used the chance to attack Roudin. He used nearly 20 points of his Essence to empower his Sword Return, otherwise, he would have never been able to reflect that squall just now.
After using Sword Return and targeting Roudin, he immediately used one of the charges for his Enhanced Instantaneous Movement to avoid the other squalls. While some of the squalls crashed into one another, there were still four squalls remaining from Sage's initial attack that changed their course and headed straight for him.
When Izroth saw that Roudin was immobilized by the squall that he redirected towards him and that Sage had no longer paid him any attention, he twisted his body during his retreat towards the Boundless Sea and brandished his Sword of The Storm.
