Running Vanaspati, everyone but one of the DPS and myself die to the meteors. I use Nascent Flash and Shake It Off to try and keep them up, but it's just not enough, so I take Svarbhanu on from 15% by myself. Pull out a win through sheer moxie.
Same deal in Malikah's Well against Storge, but due to his lower unavoidable AoE output and the DPS being a melee (so access to Bloodbath) we were able to get him down from 30% as a duo.
I know there's a lot of hub-bub about how tanks have OP sustain and healers can feel superfluous in Endwalker, but damn do you feel like a badass after pulling that off.
