Try Precognition on both bars when she grabs you (Psijic ultimate morph). Could also try a companion tank or healer, I suppose.

EDIT: I assume you actually mean Spire of the Crimson Coin. I found it. Precognition does not work in that fight, so don't bother. However the group boss does very little damage to a purpose-built solo character, such as my stamsorc with whom I went there. My character has about 2K health regen from Strategic Reserve and passively heals from Crit Surge while Hurricane, Caltrops and Stampede are up. Health barely drops during the CC phases.

There are many ways to slice this. Get some health regen from, say, Gaze of Sithis and Endurance jewelry. Alternatively wear Pale Order and DOT the boss up good, so Pale Order keeps healing you from your damage over time. Perhaps simply use a class that has HOTs (heal over time) from damage, such as Swallow Soul or Burning Embers. On the other hand just having enough health and a healing skill seems to be enough. I dropped Strategic Reserve for testing (so no health regen to speak of). My character has 35K health and about 20K resistances with Vigor. The boss dropped me down to about 40%. One Vigor afterwards basically restores your health. Tested without Crit Surge running in that case.

Please refer to my edited first post.

You might be actually thinking of the Crimson Mother on the Spire of the Crimson Coin public dungeon, that is the one that locks you and drains your health.
And, for that one, you front bar a heal over time, and keep it up at all times. If you are a warden, the bear occasionally interrupts her and frees you.

Yep, this or spec out your companion as a healer to save you. Both work

Halodid broodmother is both a wb and she is also in the ghost haven public dungeon.
Just thought i would clarify that

Thank you all for your help

I've done it on my sorc. Crit surge plus a dot kept me alive through this phase.

I haven't managed it on any of my other characters, though.

I did it today twice on my sorc with oakensoul 1 bar build...was easy.
I got the lead and was able to finish my woodworking station from antiquitìes.
Thanks so much for your reply 😊

Just out of interest: how much health does it drain?

the crimson mother boss drains for about 5-10 sec, as long as you can survive that your good, but the drain is pretty high dmg and you cant cc break out of it on your own

a melee companion could interrupt (if they arent dead) or a healer companion could get you through it

or just build tankier with a set like leeching plate

the hadolid group boss in the other public dungeon doesnt have any kind of unbreakable cc move, its just very annoying with health % triggered invulnerable phases

Thanks, that's the answer I was looking for regarding the Crimson Mother boss.
I've fought the Hadolid Broodmother a few times, it's not too tough, but as you said the invulnerability phases tend to slow down the fight a bit.
