How to beat Braccus Rex?

[K.A.]

He summoned a rain of fireballs right from the start and then my whole team got slaughtered. My party is already level 9 but that prick hits like a level 20 character.

His first attack is guaranteed to hit unless you have something else to be hit by him (like a fire summon for example). You need to summon and then trigger the dialog. This will need a bit of training to get it right. For the party to survive the first attack you need to not pack your party. Of course having 100% fire resist or close to it makes this opening attack a walk in the park and the fight also much easier. Casting rain before engagement helps for this. Mans-at-arms Elemental tortoise can easily get your shield warrior to fire immunity. Aside from that, the standard pattern is to let one of your guy die (maybe he could still have a bit of HP) and ressurect him afterwards (there is a scroll for that purpose on the right altar close to the entrance). Then comes the fight. It's better to fight one boss at time. They are mostly weak against water spells and most heals from fire. You can make the door a chokepoint area. It's very efficient. After all 3 bosses are dead, Braccus himself will come at you. On tactician difficulty there are 4 cristals to be destroyed before being able to deal even 1 point of damage to him. In that case you want to timely range attack the cristals as much as you can while kiting the bosses. Braccus is rather weak to control spells. Abuse them (one at a time) and strikes at him until dead.

WARNING, CONTAINS SPOILERS!!!!

IGN gives a nice walkthrough at their site ( :/www.ign.com/wikis/divinity-original-sin/Part_6%3A_Fighting_Braccus_Rex) which I partially used to defeat this boss.

It shows a lot of info mentioned in the previous reply; especially using the door as a bottleneck.

When doing this fight (curently playing classic mode), I had one SH mage (pyro), 1 SH ranger, Bairdotr and Jahan in my party. Imho, Jahan is a must, considering how much fire damage you need to deal with.

What's very useful is Dual Wielding wands. Whenever possible use a wand doing Air Damage and one doing Water Damage at Jahan and Earth and Fire (later water) damage at my SH mage.
Because of this, you're able to deal 2 various kinds of damage at the cost of "only" 4 action points; but more important, you're finding out fast which resistances an opponent has. (You can use the examine option as well, but I found attacking them works faster).

I can't exactly remember how I did that fight, but if I'm not mistaken something like this:

1) Send in the person with highest HP and highest fire resistance. Leave test of the party behind the door in the hallway.

2) Summon something as close to possible to Brachus. If this doesn't trigger the convo to start, move very slowly forward until it does. You might do a quicksave prior to each "step" to use RNG in your advantage

Now you got two posibilities. Brachus attacks your char or the summon. If he attacks the summon, retreat to the doorway and hook up to your party.

If Brachus attacks the char doing the convo, that one most likely die. If he does, no worries.

3) With that char dead, have one of the others use a ressurection spell to bring the char back to life. If you got the ability to use a 2nd mage, let that one heal the ressurected char.
This will trigger the other ones to attack you.; however they still need to cross the entire area and - more important - Brachus doesn't follow them!

You might considering casting a rain spell first; however, while it does protect you somewhat, it also hinders the fight against two of the summoned minibosses.

4) Using the door as bottleneck, kill them off one by one. I had that lighthouse dude attacking me first, which gave me a nice poisoncloud, which I set on fire, doing lots of damage to Diederick.

5) By the time Diederick was killed, the Twins attacked me and I had my 2nd mage back to full strength.
Both the twins and Brachus are vunerable to water, meaning you need to cast a rain spell to counter their attacks. After that, using some water and air spells, as well as using silver, freezing and water arrows at both will put them down quite fast.

Hope this helps,

Thorin :)

The easiest way to beat Braccus is never to have him cast his meteor spell in the first place. Sneak one guy into his room (you don't actually have to use the sneak function...by 'sneak,' I just mean, don't go near enough to Braccus that he actually sees you), throw a candle into the ghoul to make it burn, then run back to your allies at the door.

If you do that right, Braccus' minions will chase you to the door while Braccus himself stays still and doesn't do anything. After all his minions are dead, then Braccus will chase you. But he will never cast his meteor spell.

Interesting because in my fight Braccus Rex didn't particpate until after the others were eliminated. I think I was out of his vision because I backed through the door that I had entered the fight to. Cast a spider just on my side of the doorway to draw in just one opponent at a time so to speak. I believe I had 2 lone wolf mages at level 7 or 8 at the time. Both with summons, which is the easiest build to play.

My first play through, I missed the key to open the gate to get to Evelyn so didn't fight Braccus until I was probably level 12. Obviously that was easy at that point. Keep in mind you can always skip Braccus until later unless you really need the drops. I don't think what he dropped was too good though iirc.

[K.A.]

Thanks guys. I'm gonna try.

When i got here the exact same thing happened and the entire party was wiped by the meteor strike and i was thinking WTF i didnt even get 1 turn. So second attempt i unchained my tank from the party with some fire resist and initiated the fight with him. The meteors didnt hurt anyone else and the fight wasnt too bad.

I like to get as much XP as possible, so I'm at level 10.
Have as much fire resist as possible on each char.
Wait till B.R. walks closest to the entry door, cast rain, then engage him.
After his supernova sun attack, activate the bloodstone that my highest initiative char. has.
