What am I missing? We went there with 2 Relic+1-equipped DDs, and mostly couldn't get the adds down in time. Boss absorbed them with too many hitpoints and got buffs and did fat Blood Rain attacks. And even when we survived those, she had too many hit points left and her final attack series killed us - either the constant whole-room action lock + fire 4, or the single-person pull + instakill.

We cleared Pharos Sirius blind without too much trouble earlier. Haukke is supposed to be easier.

We didn't actually save any of the wood wailers in the first part of the dungeon. Does that make a difference?

We're completely stymied.
