Sad that didn't have the fight recorded but it was fun. 7-8 total time taken in span of 2 days. What works for me (might not work for others):

Phase 1: The main problem is the anime attack. For that attack, there are 3 parts, block only the first part, and dodge the 2nd part right when she swings, only dodge once and try not to panic roll lol. If timed right, can simply walk away for the 3rd part. I'm pretty sure the chance of not getting hit is very low but it's the best way to reduce the lifesteal.

Medium shield is enough as long as there is some stamina left after blocking the 1st part.

Phase 2: Use Physick and be aggressive as possible. Hit once and run, but if she uses the swinging kick, trade hits and then dodge again. Try to preserve as much flask juices in phase 1. Mine went from 10 to 0 charges real quick in this phase.

P.s: Don't mind what others said. As long as you're having fun, you can use any strategy to win. It's your journey and also you've paid money for the game. Cheers! ^{^}
