Echo of Lilith Eternal Realm No Fire orb hit Barb example?

Hey fellow console wanderers, i have been struggling with echo of lilith using a Rend/Charge barb. The issue is that no single mistake is allowed for phase 2 fire balls. All video clips I saw were either build crazy tank or uber selig. Either means it seems they took some hits and could survive. Just wonder if there is any “clean” run or dodge to showcase no fireball hit is possible? Cheers
