Summary
In the final battle ofBaldur’s Gate 3, players seek out the Elder Brain and face them down in a fight to the death. They don’t have to face them alone, because every Tav or Durge meets various characters along the way who can become staunch allies and join them in the final fight.
The players will gather these characters as they enter the final stage of the game thanks to a mix of quests, dialogue, and other various interactions. Everyone meets in one of the few intact castle rooms before the final battle, so the party might not be aware of who can help them until that moment.
Updated July 31, 2025 by Kristy Ambrose:Baldur’s Gate 3 cemented itself in gaming history when it swept The 2023 Game Awards, and the winning streak continued in early 2024 and even to the present day. The game still has a special place in the hearts of gamers and retains a consistent and active player base. There won’t be a sequel or DLC from Larian Studios, but the incoming Patch 8 will include some extra subclasses, bug fixes, and crossplay options.
20Arabella
Bring Her To Camp, Find Her Parents, Meet Her In The Sewers
It may be a surprise that a young child can be a big help inBG3’s final battle, but it becomes increasingly clear throughout the game that Arabella isn’t a completely ordinary tiefling child. Getting Arabella as an ally should be relatively easy for most heroic parties, as they will need to side with the Tieflings in Act One and help Arabella find her parents in Act Two.
In Act Three, where players can find Arabella again in the sewers, she will agree to help them. She will grant players Freedom of Movement for the final battles, which negates the movement effect of difficult terrain and prevents the players from being restrained. This is particularly helpful inthe big fight on top of the Netherbrainas the movement becomes essential.
19Duke Ravengard
Finish Wyll’s Companion Quest
Players only need to do one thing to recruit Wyll’s esteemed father, Duke Ravengard, but it is a tough ask. Ravengard spends most of the game kidnapped, and this culminates in Act Three when he is restrained in Gortash’s underwater prison, The Iron Throne.
To get Ravengard as an ally, players will need to rescue him safely from the prison. This can be achieved by getting Wyll to stay in his pact with Mizora or simply by trying to free the Duke without aid. This will upset Wyll’s devilish patron and make the task of getting Ravengard out of The Iron Throne even more daunting.
Doing so successfully will grant players the rallied condition for the final fights, a stronger version of what they are likely to have seen Zevlor use in the Druid’s Grove in Act One. Ravengard’s rallied condition blesses characters with a whopping 30 temporary hit points, and each hit point can be the difference between life and death.
18Volo
Save Him From The Goblin Camp
Volo is always amicable to the party but as a controversial figure in the Far Realms, he often needs rescuing from various precarious situations. To officially get Volo as an ally, players will need to rescue him from the Goblin Camp in Act One. Volo can then be rescued again in Act Three, where he is tied to a cart full of explosives by an angry mob.
Getting Volo as an ally grants characters an ability inspired by his infamous works, Volo’s Guide to Monsters. Proving that knowledge is power and forewarned is forearmed, Volo’s information grants players a +2 to attack rolls, saving throws, and ability checks, an overall strong buff to have to go into the final few battles.
17The Kuo-Toa Acolytes
Loyal Followers Of Their Chosen God
There was an obscure part of the Underdark just north of the Wizard’s Tower that many players didn’t find until they had explored the area several times. It’s in a subterranean location that can only be accessed by a tunnel surrounded by explosive mushrooms, but if a player ventures there and passes some difficult Persuasion and Wisdom checks, they can become their new god and recruit them as allies in the final fight.
As the deity Mahkloompah, the protagonist can summon four Proselytes, two Devotees, and one Champion. The Proselytes are melee fighters that do physical damage, the Devotees have combat abilities like Blood Frenzy, Claws, and Net, and the Champion has all of these skills plus Divine Smite. They’re squishy, but there’s nothing more powerful than a true believer.
16Halsin
Save The Grove And Lift The Shadow Curse
Players who are fond of the lovable druid companion, Halsin, will be pleased to hear that he offers a unique benefit as an ally in the final battle. Halsin grants the party +1 to all ability scores, potentially increasing everything from attack bonuses to armor class, and adds +2m to their movement speed.
This can be essential in the final fight, which involves reaching one side of the combat arena as quickly as possible. Gaining this bonus is as simple as recruiting Halsin by protecting him in the Druid’s Grove, lifting the shadow curse, and having him in the party for the final battle.
15Mol
Save The Refugees, Then Find And Return Her Contract With Raphael
Mol is one of the more enigmatic and independent characters ofBG3, being one of the few NPCs that doesn’t need the protagonist’s help to survive, but she’s willing to accept or give aid if the price is right. She saves players from Jaheira’s wrath at Last Light Inn and manages to escape the Grove and the Shadow-cursed Lands. Fans can meet her there, with some of the other Tieflings, and find out about her contract with Raphael.
In addition to better Fire resistance and saving throws, Mol also gives the party members the power of Fetcher’s Favor. They can cast the level 2 spell rays of Fire, which can hit up to three enemies at once.
14Bhaal
Honor The Murder Tribunal And Defeat Orin
It makes sense that the Lord of Murder could make a powerful ally for players who can impress them.Dark Urge playerswho make the terrible decision to give in to their bloody fantasies and become the progeny of Bhaal can gain their sinister “father” and patron as an ally.
As evil as this route is, Bhaal does grant his faithful some powerful abilities. They can cast Stunning Gaze, and the number needed to roll a critical hit is reduced by two, which can stack with other effects.
13Kith’rak Voss
Obtain The Orphic Hammer And Pass A Persuasion Check
The githyanki Kith’rak, Voss, can be quite an unexpected ally in both the battle against the tyranny of the githyanki goddess, Vlaakith, and the final battle. As an ally, Voss calls his red dragon mount to rain fire down on a specified area. To gain Voss as an ally, players must defy Vlaakith in the githyanki creche in Act Two.
Voss will tell players he also wants to dethrone Vlaakith and reinstate the mysterious githyanki prince, Orpheus. In Act 3, Voss can be found in the sewers, and he needs players to free Orpheus from the Astral Prism using theOrphic Hammer. Orpheus himself also makes a good ally, but Voss can be convinced to help players who side with the illithid Emperor over his prince, although it is tough.
12Rolan Or Lorroakan
Give Up The Nightsong Or Replace Lorrokan With Rolan
This ally ability is identical depending on whether players have gained the alliance ofthe tiefling, Rolan,or the sorcerer, Lorroakan. Admittedly, Rolan will be the better option for heroic runs, as his recruitment involves saving the tiefling refugees, saving Isobel, and confronting Lorroakan.
For players with a slightly more sinister run, they can recruit Lorroakan if they hand over the Nightsong to him. Both allies have the identical ability to summon a firestorm on the battleground that does serious damage.
11Mizora
Finish Wyll’s Quest And Bring Her To Camp
Wyll, the warlock companion character, has a devilish patron called Mizora. She can be recruited as an ally for the final fight if players rescue her in Act Two, keep Wyll in her pact, and tell her that they need something in return for letting her stick around in their camp.
Mizora is a powerful ally to call onto the battlefield, capable of demolishing her foes, and it is worth recruiting her if players are willing to forsake Wyll’s sanity. She has a variety of talents in battle that can be compared to a Sorcerer, with a similar spell list along with abilities like Metamagic: Twinned Spell and Heightened Spell.
