Tanking Resurgent Cryo Regisvine

Defeating the final event on Dragonspine in genshin impact Bennett Diona Xingqui and Fischl Frostborn Miracle is an event where you have to fight a Cryo Regisvine except its on steriod. It has a move that suck 1/3 of your HP every second and if your not careful or in safe zone you would fall almost immediately. Thankfully Diona+Benette heals can over power the damage depending on your build. My Diona is on Nobless with Regen/HP/HP while Benette is just plain Witcher Atk/Pyro/Crit
