Starhawk64: So, what would be the optimal party build and size?
I'm thinking of a party of four with three dual-classes and maybe a bard or paladin.
So maybe something like this prehaps:
Fighter3/Cleric
Fighter3/Theif
Fighter3/Mage
Paladin or Bard
From the standpoint of soaking every last XP out of the game, you'd need a Paladin and a Bard. But it depends on how many characters you want to have in your party.
I figure a party of 3 characters would be sufficient to cover all the bases though. A Human FTR dualled to Cleric, a Human FTR dualled to Mage and either a FTR/Thief (dual or multiclass) or a FTR/Mage/Thief. You'd miss out on a few quest XP in the beginning without having a Bard and there's a pretty hefty award you can miss out on without a Paladin later on.
Personally, I like to also have a Druid (probably FTR dual classed to Druid) because I really like some of the spells in the Druid spellbook.
