I can't keep up with it on the third phase

[LordBingShipley]

If people cant keep up with perfect blocks, just sit there and hold the block. Yes you'll eventually get stunned, but thats better than taking tons of damage. Also, hold block when she screams, itll stunn you but refresh your shield stun bar. The Fire Ant shield and Tick sword made this boss easy

[DatboiZyion]

A useful tip for those who are not that good at blocking: I recommend trying the shield solidifier. It increases your blocking strength by 25% and can be useful when just holding the blocking button. It’s also easy to get, being found in the wormhole container inside the brawny bin. You can easily pick it up while grinding for the wasp queen, though it can be easy to miss if you don’t have a light.

Great guide, sadly the pause to heal trick doesnt work when playing in multiplayer xD

[lazyloser]

I hear people talking about shields and toenail scimitars yet I’m here with a mint mace and smoothies

[davewright]

Damn, I didnt realise you could change the difficulty mid game. I kept getting killed in phase 3 last night on medium :(

[stephenshaffer]

Good show man. It was nice to watch without the stress going to do this right now.

[fingleberry]

I come back a long time later, I am a changed man for I have beat the infected broodmother and moved on to new game plus, use a fresh toenail scimitar, and once it hits 3rd phases just hold block on all attacks, if you can Parry them then do it, but what you want to do when you block is about to break is block the scream, it will most likely break it and sets you back to a fresh block, in-between start chipping off at her and you will get it

[Alistairdavidson]

Thank you so much I was able to use this build and kill her on my first go, luckily I also got the golden creature card on my first aswell

[DJF-dzxg]

I wanted to thank you for this cause of your tips me and my father was finally able to beat this damn demon on Mild

[lois-_-]

Great video and another tips : sleep in the petals bed (i think its is name) so you have the resistance and energy bonus.

[XRElectric]

For some reason my worst phase is phase 2. I activate ultra instinct in phase 3 and somehow have no problem tracking her and parrying her attacks

[PipHalsey]

Note: it seems you can no longer spam smoothies like that, they have a cooldown now. But still, this guide helped me beat the infected broodmother.

[CharlieBeardsley-lg]

I’m only trying for blaster of moldy matriarch because I’m about to go into new game and I’m too lazy to keep making bratbursts

[thematrix]

I copied every build that’s shown on YouTube and failed to kill the IBM, 3 hours I tried and failed every time BUT i copied your build and I liked the advice you added thru the fight and I beat her 1st go after watching your vid so thank you very much sir. I will say round 3 of the fight she’s deadly but blocking was the main tactic I used in round 3

[gennaroliguori]

very good guide bro, thanks for the upload

[WNTER_SF]

Just get the badge that heals with parry that's what i used and 5 hits combo heal so much the fight becomes easy

[nungkyayusopiany]

How should i do the perfect block if my computer is so laggy

[RiekaNicholas-didt]

Medium difficulty also let's you pause while in the inventory, at least it does on mine which is single player on console. Also as of the recent update there is now a cooldown on smoothies that won't decrease until you leave the menu

[pierrepellerin]

your infected broodmother seem tame somehow. Mine is relentless. phase 1 and 2 is fine but in phase 3, there is no pause. It's hit after hit, dust everywhere and explosions all over.. And you can't spam smoothies anymore.
Beating her is the only thing I have left to complete 2 achievements. To one to beat her and Burgl quest list no 100 is to beat her. She is also part of the 100% completion now but I got that before she existed.
Try no 4 tomorrow...
