Okay, this is an incredibly tough fight, but here are some basics that might help out:

Before you double click on the pit to make him show up, cast as many defensive spells on your party as possible, and make sure to pause (i.e. give everyone their casting instructions, when they're done casting pause the game... give them their next casting instructions, they cast, pause the game) this will ensure your 1st cast spells don't wear off by the time you're casting your last round. Also, if you haven't already, you may want to go to the options page and set the playing options to pause at certain points (when a character takes damage, when they are attacked, when a spell is cast, at the end of the round, etc) so that the combat becomes more 'turn based' in style... it's a LOT easier to keep track of what's going on then, to pull the badly wounded out and heal them, etc.

Make sure you cast Free Movement, Magic Resistance, Protection from Fear, Protection from Evil, Haste, Spell Turning or Spell Shield and anything else that might protect you BEFORE the battle. Also, summon as many creatures (Monster Summoning III, Earth/Air/Fire Elementals, etc) as you can (it will only allow you five max) to sort of 'pen in' Balor as your mages whallop on him from a distance (I don't remember if magic arrows do damage or not, but it's worth a try). Clerics can also cast Holy Smite, Bolt of Glory, and other damage-at-a-distance spells while this is going on.

I hope these things help... let me know how it goes! [img]smile.gif[/img] Good luck!
