1st Event Boss Platinum - Hydro Dragons, don't cry!

Doing the other bosses with Platinum gave me the motivation to retry this one. Team is Neuvillette, Kazuha, Furina and Kokomi.
Biggest issue is the massive damage the Regisvine can deal. Neuvillette has the advantage to go at a distance but there's still a onetap potential.
I needed buff food again but instead of HP I used Lyney's signature dish for more crit stats.
