Any weakness's or weak spots on the damned brood mother?

I have shale, liliana, and the dwarf you joins you.
Liliana is using a bow (A dlc bow, brenegans bow?) with arrows that do nature damage, and in leather armor (I have nothing else she can use).
Shale has some electric crystals, and I have no clue what the other side even does. I have some fire crystals, spirit crystals, and some stronger spirit crystals. He is now wearing some kind of white crystal, I forgot.
The dwarf has his default armor, but I replaced his axe with a nug crusher.
I wear the dragon blood armor, have an enchanted dagger and the star longsword.

Ok, tried about 10 more times. I managed to find a few more potions, I can keep my guy and shale alive till the end, maybe liliana if I'm lucky. She always gets me on her second wave of darkspawn, me and the archer always focus on the darkspawn, while shall continues to fight the broodmother. The dwarf always dies the first few minutes, due to his very low constitution.

When I fight the broodmother, I always gather my whole party on the small island where she can't shoot her tentacles directly, make ALL of them use ranged weapons, and attack the brrodmother from there. You might need to let one party member switch to melee if any of her tentacles spawn close enough to reach you, but otherwise just continue like that.

Once the other darkspawn arrive, you switch to melee and fight defensively on that small rock "island", until they are dealt with. Then you just continue with the ranged weapons as before until she is dead.

I distantly recall using my mages to cast a few Primal spells to kill her. For all I know, I cast Storm of the Century. Regardless, the areas behind her are relatively safe, as her tentacles are unable to reach you and all she can do is spit (which somehow can go through walls).

Thanks for all the help, but after about 20 more trys I gave up and just used console commands.
