You can chain invulnerability frames from Miriam's Vanishing into Bloodhound Step.
You have to start running within half a second of the attack animation starting, then Vanish into BHS to get out of the storm, then almost immediately Vanish into BHS to dodge through the laser.
Do not, under any circumstances, use this video as an argument of "see, you CAN dodge it" to defend this boss design. This is abject nonsense.
