Elden Ring: Any reliable strategies for consistently dodging Malenia's Waterfowl Dance?

I'm on my 50th attempt against Malenia and her Waterfowl Dance is absolutely obliterating me every single time. My current build is a pure strength colossal weapon user, and I can usually get through the first phase, but that move in phase two just ends me. What specific tactics or timing tricks have you found most effective to survive it without taking damage? I'm open to any advice to finally beat her!
