Illithid Powers, also known as Tadpole Powers, are a type of special ability in Baldur's Gate 3. Illithid Powers are tied to the Mind Flayer tadpole implanted in the heads of the player character and Origin Companions at the beginning of the game. Some Illithid Powers are available to all classes, while others are class-specific.
How to unlock Illithid Powers in BG3
Illithid Powers are acquired by selecting [ILLITHID] [WISDOM] dialogue choices when interacting with other NPCs, usually those who are also infected by an Illithid tadpole, but disciples of The Absolute also tend to trigger these dialog options. Once the player has succeeded on 3 Illithid Wisdom Ability Checks, the next Long Rest they take will trigger a dream cutscene (the trigger for this dream may also be related to the cutscene seen in the Goblin Camp). If the player choses to make use of their parasite in the dream, they can then consume any Mind Flayer Parasite Specimens they may have collected. This will trigger another cutscene about consuming the Tadpoles, after which any future parasite specimens the player finds will be added directly to the Illithid Powers tab in the Character Sheet.
How do Illithid Powers work in Baldur's Gate 3
After obtaining an Illithid Tadpole from other infected NPCs, you can spend them to unlock an Illithid Power of your choice in the Illithid Power Menu by pressing B. This menu is set up similarly to a skill tree - Illithid Powers in the outer ring of the 'tree' can only be unlocked after unlocking those adjacent to it in the inner rings. Illithid Powers with grey icons are passive skills, while those with red icons are active skills. Once in the Illithid Power menu, click and drag a tadpole from the top right corner into the skill you want to unlock. You will have the Illithid Persuasion unlocked for free.
It should be noted that some Illithid Powers were class-restricted in the Early Access version of the game. In the final release of Baldur's Gate 3, this restriction was lifted, and all Illithid Powers are usable by any class.

Tadpole Locations for Baldur's Gate 3 (BG3). Each parasite consumed unlocks one new Illithid Power within a skill tree of 25 powerful mind-flayer-inspired abilities, completely separate to the options you have when you level up in a traditional sense. These are divided into five branches themed around manipulation, health restoration, psionics, and abilities that can inflict immense damage and torment enemies to gradually weaken them over time. Some abilities can be used to control those around you, pushing them to say things in dialogue they would otherwise not. Others endow you with the power to push and pull enemies like ragdolls during battle.

So, 7 (8 if you betray Nere) in Act 1, 12 in Act 2 (+Astral-touched tadpole) and 23 in Act 3, maximum 43. You need 25 (20 with Astral) to one character was everything.
If you're playing with friends and want one character with full potential, you have 23 free tadpoles.
So everyone can have at least 5 illithid skills and first 5 of them will be free when you have Astral tadpole. Don't bother arguing about "who is first" in your group.

the way to unlock the illithid powers is misleading. you don't have to use the [illithid][wisdom] commands at all you seem to only need to trigger the scene with the absolute at the goblin camp. I started a duergur barbarian character so I didn't have to use the illithid powers to free shadow heart, went straight to the goblin camp again without using the the tadpole (just intimidation because you know barbarian), and after the cutscene with the absolute the dream visitor approached me and i could start unlocking powers.

there are some more in the gith creche, in the lab where they try to "cure you" on the work benches.

Possible bug, or new parasite location in Act 1. Sitting at 5 parasite points having only collected 4 tadpoles. My best guess is the mindflayer's quest in the underdark silently rewards you another.

there are more illithid powers unlocked by using the [Illithid][Wisdom] dialogue option multiple times.

According to the lore , We should get one tadpole by killing companion npc.

Your character said NO , your normal sense still said NO (whose sense said yes , go to eat raw meat and get parasite to your real brain)

Perilous Stakes - DO NOT SLEEP ON IT
If it lands, legit overrides immunities to any form of dmg and makes them take 2X the dmg from ALL sources for 3 turns. The hardest hitting single target debuff for bosses, especially good if you're fighting an enemy who is immune to your preferred dmg type.
Best part is, it's not technically a debuff so the enemy doesn't get to roll for a save. So damn good.

In act 1, one can be given by True Soul Nere if you kill all the duegar first (don't know if im spelling that right and too lazy to look it up) and then detecting his thoughts. The option to to say that you solved his problem comes up and choosing it will have net you a free tadpole. Note that you can also kill him for the tadpole in his head

Astral tadpole use is great for weak characters (low strength)
Main reason is it automatically gives the Fly ability, WITHOUT spending any tadpoles.
This helps to improve their jump distance without constantly having to have a strong character throw them or cast Fly / Leap
- Anonymous
So apparently there are not consequences for using some of these things...
Are you telling me I went through all of Act 1 taking care by not consuming them for no reason? Lmfao

anyone getting random free parasites since patch 1.2? not small amounts either, I jumped from 11 to 17 near end of Act 2, just doing House of Healing and approaching the Mausoleum. crazy bug if so

We should be able to kill our companions in dark urge to get their tadpoles.

Does anyone know what the save DC is based off of? I can't seem to find it anywhere.

It should be mentioned, that if you pass some of the kills to join the Absolute, you still get the tadpoles. E.g., if you side with the Goblins in Act 1, you will get as many Illithid Powers as "Gift by the Absolute" as you missed by not killing the bosses (works as a mix, too - not killing any bosses gave 3 Gifts, killing Priestess Gut resulted in one looted tadpole + 2 Gifts). Same for True Soul Nere.

The Act 3 entries on the list here are really vague and aren't linked to pages about their location like Act I and II.
It would be amazing if someone who knows how/where these are would clean the bottom section of the page up as finding these things can be really tedious. :)
Thanks!

> Three can be found at Infirmary, Creche Y'llek
The creche is in act 1, not act 2. The Monastery is a part of act 1, evidenced by the fact you can freely travel between the grove, underdark and Monastery

In act 3 You can get a jar from High security vault number 6 in act 3

There's an additional power to be gained from Omeluum that I don't see in this list, presumably because it's not on the Illithid Powers screen. It's called Survival Instinct. "Infuse a creature with psionic force. If it reaches 0 hit points, it heals [3d4] instead of falling Uncoonscious."
I got it by succeeding the first check, but failing the second. Won't spoil anything else, and don't know if it is unlocked by failing the first check or succeeding both.

How do you unlock Illithid powers for Shadowheart and Wyll? I can only use them on myself and Asterion currently.

Make sure to get the permanent passive skill by absorbing the powers of the zaith'isk device inside the githyanki infirmary.
Awakened Passive Feature
Effect: You can use all of your Illithid Powers as a bonus action.
This will make most of the action skills, that sucked, absolutely incredible especially if your PC isn't dual wielding.

But is it ok to use tadpoles on Astarion? Will he go crazy if you give some of them to him?

So if I'm reading correctly.
1st layer powers = OK,
2nd layer powers = Watch it buddy.
3rd layer powers = Hope you like the taste of brains.

there are two tadpoles in a wooden crate on the stone lord boat to the east of rivington in act 3.

A SPOILER regarding tadpoles, and a let down for people who like me were planing to not use them. You will get nothing for remaining pure, some occasional quips in dialog that you are still refusing to use them but that's it. No achievement for it, no super special hidden gear or even a special ending for being pure. There is a danger if you go overboard but it's telegraphed and flat out told to you if you take the next step it will change you , that's when you will see/face some consequences but if you simply nope out at that point and don't go into the next step, you get to enjoy the first level tad pole powers without any cosenquences.
Basically, a pure run is more of a i suppose a "challenge" run in a sense, granted you don't need the powers, without em' if you know what you're doing to a degree you'll still be fine-ish, but you are dropping the potential of further exploring and having fun with some more cool powers and buffs for basically nothing.

Interested in learning if it's an all-or-nothing decision. I initially 'succumbed' but haven't actually unlocked anything on the skill tree, yet NPCs act like I'm fully invested. Will report back if I make it to the end without using them

16 tadpoles after two acts for me, part of them just random dead npc
Btw also important note: if you pass magic check for githyanki "heal" stuff, all illithid powers which consume action will be consumed bonus action.

Everyone looking at this page as of Aug 5th please keep in mind it is outdated. All of this information was from the Early Access and so much has changed. Most of it is untrue now. For example, there are no long class specific illithid powers. Moreover multiple are now locked behind much later parts of the game. Don't take this page at face value until it is more updated with more recent information <3

I got wrong power for my class. I have abjuration wizard and I got cleric class skill. IDK why it happend...

You know, for a skill tree that is supposed to be a tempting lure of power with severe consequences, almost all the skills in it are just kinda "meh".

so is each parasite limited use to one person or can two people benefit from one, from the jar with one example, could both me and my friend consume/benefit from it or only one?

What if you multiclass? Do you get all the class abilities that are offered?

Any impact on the storyline? I'm thinking of not using this. There's probably an ending for fully rejecting these powers.

So the monk its the only one that dont have a special power ?
If you save Isobel at the Last Light Inn from Marcus, and then kill her, you can find a tadpole on her after the battle with Ketheric Thorm.
