Any ideas on defeating netherbrain?

[GmanUK1965]

So I'm stuck where you have to get your characters to the crown and use netherstones. I've looked at youtube and they all seem to use invisibility on all their characters but whenever I try it just gets countered every time. I'm using 2 wizards, shadowheart and asterion.

maybe i got lucky.. on turn 2 all the bosses below dead.. the emperor, his dragon and some guardian. then i work my way up to those mindflayers. however those MM is really painful.

have someone cast dome of invulnurability over the portal opener

This, for sure. In all of my playthroughs, this has saved my ass every time. Almost guaranteed win, as long as you can get there quickly and in one piece.

Unless a mindflayer casts some mind spell on the character controlling the dome of unvulnerability and cancels it as happened to me. If ice storm is cast onto dome there is a good chance dome controller slips over thus cancelling dome. The dome conrtoller never left dome in both of these occasions

I managed to get three of my characters through the portal only to be met with another problem. Every time you damage the brain it damages you back and sends something over the character's head. Next turn it destroys the platform your character is standing on killing the character. Two turns and all characters dead

I've played 428 hours in this game so far which includes EA and this is how it ends. I am now on the brink of giving up unless I load up a game of 5 or 6 hours ago

You need burst damage to take out the netherbrain fast. Disintegrate and other force damage is key.

I just go solo, no Allies and no companions on tactician, I kill everyone in 2 turns, have the emperor open the portal then go and kill the brain the following turn.

It’s a LTP thing you probably have crap team and crap gear and some sort of crap netdecked multiclass as a main

[Scottx125]

Literally the easiest boss fight in the game.

Sure, I suppose that's possible as well. Maybe I've just gotten lucky, but that has yet to happen to me. I suppose this could be negated by casting it on the same turn your caster moves inside it.

I've reloaded way back to being at camp after defeating Orin 4 hours back. I have also deleted every save above that so no choice now and play from here

I also need to find lots more GP. 5 Disintegration scrolls at 6000gp is a lot

Why are you listening to that one tip over all the other good advice here?

[VastGirth]

I didn't rush it.
Summoned lots of help in the middle to distract the dragon and mobs.
Left Asterion and Shadowheat where they started, doing more spells and summoning.
Slowly worked my way around the outside with Gale, Tav and Orpheus, taking out the mind flayers on the way
Cast dome of invulnerability on my tav when he was channelling.
Wailed on the brain till it was dead.

Wasn't too hard tbh.

Most of the advice given hasn't helped and I'm thinking I am missing something and the only way of rectifying this is to go back main Baldur's Gate to find things I have missed

The magic heavy party is probably making this fight a little harder for than for a melee heavy party. The enemies are pretty spread out, so it's hard to tag a bunch of them with AoEs and, unless you're playing a lightning charge mage, you just don't have the single target damage per turn this fight needs. If you learned the spells from the forbidden books in the vault of Ramazith's Tower, those might help.

Anyway, the amount of damage you need to inflict to kill the dragon will kill every other enemy on the map. So, to reduce the number of actions the enemy has, kill all it's adds first. Starting with those hard to reach mindflayers. If Astarion is well built he should be able to kill two mindflayers a turn for you. Since you have mages you can try dominate person to get the enemies to kill a few of the adds for you.

It is possible to apply Invisibility before ascending to the final arena (touching the Netherbrain's appendage). The Sanctuary spell is very useful to protect the allied mindflayer (after the illithid has started casting and the party members are sitting next to the crown, just in case), though, the cleric/paladin might not survive for the portal to open. Then it should be possible to deal enough damage to the Netherbrain with 4 characters.

[Moonbane]

If you have taken illithid powers, use the mental fortress power that lets you interchangeably use actions. So you could summon allies with actions and bonus actions to summon more allies at once from each friendly within the sphere of effect.

Flooding the board with allies makes it a lot easier to to wipe the map of enemies and providing bodies to soak up incomming damage.

Most of the advice has kind of helped me but in doing so it has made me realise I have missed some interesting stuff.

Some people mentioned about summoning allies. I had The Watch, The one's that said they would aid me after killing head vampire but not finishing the ritual, and the ones that had the woman councillor as their leader. One who mentioned she would help was the young tiefling girl but she was never in my list so I don't know what happened there. The dragon (Ansur I think) how do I get that? Most of the allies I had were killed in courtyard battle so this final battle they did not help much

I need scrolls of decent damage and more GP to buy them

The reason I used two mages was because main character has not learned Dome of Invulnerability but Gale has.

So, I need:
better spell potions
to redo courtyard battle without allies
more allies (A player mentioned Ox (don't know how to get that) and Anthur
I am going back to Gortash's to see if I can find the concussion grenades

To do all of this I have to go back to a save before the no turning back part. I have deleted all the saves above this to stop me getting tempted and end up trying to tear my hair out again
