C1R0 Flins vs Dire Knuckle Duckle (5.5 Cost) 7.0 Stygian Onslaught - Genshin Impact

Hi Everyone! took me almost 3 full days of grinding till i managed to do it. problem is the boss has a very high HP and RNG on its movements. Flins is on Notsu Columbina is on SMS Ineffa on Aubade Sucrose on VV key techs: since im using Staff of Homa, u need to get ur HP intentinally below 50% to maximize the buff thats why i skipped Ineffa's shield at first rotation. also i went for low rate high DMG and prayed for a CRITing run.
