Balor: Anything holy and hope for the best.
Alternate Balor: Enlist the aid of a Pit Fiend and take out whoever comes out on top. (Pit Fiends have 18 HD and thus can be summoned through Greater Planar Binding)
The Balor's Greater Dispel Magic power makes the energy resistence and spell immunities probably pretty short-lived (since their effects are pretty obvious), and therefore probably not a good use of resources. Better to provide instantaneous help, such as healing, and defensive magic, such as Protection From Evil to ward against the Dominate Monster power (and keep hoping that the Balor just assumes your save is very good so that it doesn't waste a Greater Dispel Magic). Enlarge (both for the extra damage and reach), Haste (for obvious reasons) and Wraith Strike* (since it halves the Balor's AC against attacks by that person) are all invaluable spells against the beastie. Unless your cleric has the Spell Penetration feat, spells like Holy Word are only going to be effective about 35% of the time.pawsplay said:The wizard casts energy resistance on the barbarian, while the cleric lays on spell immunity to several of the balor's abilities. Once the barbarian has the thing's attention, the fighter and rogue attack. You might want to polymorph the rogue into a hydra... a full attack while flanking would be pretty good.
