Killing Balor

Khal

So I have a tiny issue killing the (a) Balor. (I am actually unsure if it is the name of the particular creature or just a general type of creature)
Anyway.
As far as I understand it can only be damaged by +3 weapons and higher. And as it happens my party only has one +3 weapon (usually carried by Minsc). Last time I was faced with a creature like that he did not do any ranged attacks so I pretty much kept my party far away while let Minsc do his thing alone.
This time however, the Balor does a lot of damage and paralyses or stuns everyone he sees. Thus Minsc is not doing a sufficient job or rather when he gets too much damage he freaks out and runs away (provided I am fast enough at casting dispell magic on him).

TLTR: Magic resistant monster only takes damage from +3 weapons. Only one +3 weapon in the party.
What do I do?
Any advice would be very helpful!

Where are you fighting this balor?

If its in the underdark any drow you encounter will likely have +3 weapons. There are also merchants who sell strong weapons in Ust Natha.

You can avoid the stunning and holding by casting the level 5 priest spell "Chaotic Commands" on party members.

Prebuffs and summons can be handy. In some case you must delay the fight and collect experience elsewhere to level up, if possible. And balor is not a particular creature's name, however they are not common. I left the details for the master tacticians.

The 3rd level wizard spell melts minute meteors hit as +5, I think.

Minsc's Berserk could help.

MMM will do damage. Depending on your party he can be tough, but he's doable. Make your tanks immune via chaotic commands or Rage, and go to town.

The level 4 wizard spell Enchanted Weapon creates a +3 weapon that lasts a day.

And that you can move around between party members.

Technically it's both. What you're fighting is a type VI demon, and the most powerful type VI demon is called Balor. However, because Balor is the most powerful, all other type VI demons became known as Balors.

What you are fighting isn't Balor himself, but rather a generic type VI demon (but still pretty powerful in it's own right).
