How to beat Phase Spider Matriarch?

[ApathicAlpaca]

Seems the guides I found are not up to date. You cannot kill her eggs without alarming her or the other 2 big spiders. I tried multiple times, from stealth, at maximum bow distance. As soon as any eggs dies they all aggro.
With 18 spiderlings around I cannot defeat her.
I do shoot fire at webs to make her fall down but this only works 2 times, she is NOT proned (guides say she gets prone for 1 round) and anyway she's left at the end with ~60 HP still. And one-hit-kills any hero.

Anything I missed? Can I at least somehow safely remove the eggs before the fight?

PS: Seems you can kill the 2 egg clusters on top but NOT the one at the bottom (spider is too near).
Might try to area clear them somehow.

First of all be at least lvl 4.
Next thing - wyvern poison. Sneak atack with Astarion with poisoned crossbow. It can take over half it's HP in a single atack.
To finish it off, magic can also wreak it. Just hurl thunder chromatic orbs or shoot fire rays at it with Gale. Better still if YOU are a sorcerer with Quicken Spell and speed potion in your pocket. You will demolish the poor spider in a single turn.

You should be able to get all the eggs before the fight, but do use fire either arrows or potions - it can take a little time but all should be destroyed.

i beaten her with help of permanent stealth as shadowheart, i shoot spider and then go to stealth, rinse and repeat til she died with 0 loses on my side.

This is really old one i did back when... but should still work. You don't really need anything special.

oh wait looks like i was using https://baldursgate3.wiki.fextralife.com/Vision+of+the+Absolute

i guess now you can use shield with it so it's even better. and use fire dip instead of posion cos they are immune to poison. And no clue why i was swaping weapons mid combat lol probably forgot it takes your action point.

I haven't tried in Patch 9 yet, but if you have a Warlock you should be able to send an invisible imp to destroy the spiderlings first. Even if they hatch and kill the imp, you can just summon another one to take thrm out one by one.

[Harukage]

*Sigh* spiderlings are not a problem if you kill matriach fast enough. She will hatch 1-2 clutches at best.
And you know, things like burning hands or alchemical fire clear them out well enough.
Alternatively Shadowheart in a scale armor +1 with shield with +2 AC, and Shield of Faith buff can hold them off long enough. If you want other character to focus on bigger spiders.

i just have someone with a range weapon go solo killing the eggs and when the spider jumps on the web set the web on fire and does like 40 ish damage when the spider falls. I just tested it 3 days ago For the eggs near the spider hide behind the rock and watch her aggro range and you should be fine.

[ApathicAlpaca]

Yeah I killed all eggs now before the fight but... she no longer steps on her webs......... great, no more burning it from under her to make her fall down.
Sigh.
Invisible imp is a great idea tho, will try that. Let's hope I had bad luck and she uses her webs again!

[Pan Darius Cassandra]

Also:

Shove her into the Undersnark.

Attack her with the Vision of the Absolute.

Use Shatter on both her and the spiderlings at the same time. Also, Burning Hands (any AoE spell really).

When all else fails, stealth cheese.

I had no issue sneaking around to break the eggs with long range. Once that was done I waited for her to stand on her web and break it. She fell down and I quickly initiated combat before she heals up. If she got too close, I used thunderwave or broke more web :) My party was my custom rogue, laezel, wyll and astarion. At least I think it was astarion xD Might have been gale.

I just completed a fresh run of Act1 last week. I killed her at level 3. Pally PC with Astarion, Gale and Shadowheart.

There are a couple poison resistance potions you can pick up in Act1. You can also cast protection from poison. Nothing wrong with buffing up a little for the fight.

Bless, aid, resistance cantrip can help as well.

Fight from the upper level.

-Keep your party back. Rogue stealth and cast firebolt cantrip. Wiped out one set of the spiderlings and then matriarch attacked. Since your rogue was stealthed, the rest of the party isn't in combat. Use them to focus on Matriarch during their surprise round.

-Keep your rogue and casters back. Your fighter/clerics should be armored and buffed. Rogue and caster can stealth with ease.

-The key is good initiative roll and destroying the web bridge when she is on it. Focus fire on her until you finish her off. Kill her first. Rest of the fight is a cake walk.

I found this fight to be incredibly easy once I figured out taking out the web bridges.

the ogre horn cheeses this fight easily

[DeportedFetus]

Usually fight this at three, crowd control/dropping it off the webbing if you set it on fire deals significant damage

[Fluffy_Yeti]

Arrow of Roaring Thunder. I cast Fairy Fire, then had the other 3 in the party equipped with those arrows. I shot her off the ledge into oblivion in the first round, then killed her 2 underlings. Zero spiderlings spawn.

well the first time i did this fight. it was not all that difficult. i just played my best and it went alright.

my next playthrough i got OBLITERATED. it was BRUTAL. i fell through the webb. i misclicked. i burned my team mates. i got swarmed to death. it was just all kinds of bad, everything that could go wrong did because i went in overconfident after how well i handled it my first time.

in my most recent playthrough, im not sure how, but i one hit killed it by knocking it off the web to its death. i dont think you get any exp for doing that, and no loot, but you can still loot the gem you came there for. and if you stealthed it you wont have to fight the stupid spiderlings.

luckily it only has 1 action so its not that bad if you're above level 1. preferably level 3 so you have 2nd level spells is a big help.
