Larian Studios Forums Divinity 2 - Ego Draconis (English) Help/Tips/Tricks The battle between "The evil Sassan"

Level 30, and I'm having a hard time beating Sassan in "Halls of Echoes". After taking out the 2 soldiers, Sassan shoots me with 2 powerful blast and I'm dead. I tried over and over with different strategy and it seem like i can't get away from her blast. Am i suppose to use something or maybe is it a glitch?

Please help!!!
