CranGrape: Hello! I just picked up this and IWD II and I would like to know what would be a good combination of companions for my adventures? I've never played this game before so I would like something that can get me through the game but not something that makes the game super easy if that's even possible.
Basically, you want to cover the four major roles: warrior, thief, mage, healer.
For IWD1, this means a melee fighter type (Fighter or Paladin are good choices, Ranger to a lesser extent), a Thief (although my personal opinion is a multiclass Fighter/Thief is far superior to pure Thief), a Wizard, and a Cleric or Druid.
For a six-member party, I tend to favor something like:
Dwarf Fighter or Human Paladin
Gnome Fighter/Thief multiclass
Elf Wizard (you could make him a specialist, but for a first timer, I'd go generalist)
Human Cleric (or possibly Fighter dual classed to Cleric at level 3)
Human Fighter dual classed to Druid at level 3 (this is a very difficult one to pull off, since you need such high scores in multiple attributes, but Druids have some great spells) Failing the dual class option, go for pure Druid.
1/2 Elf Bard (this guy acts as a secondary mage, the party 'face' whom you use to interact with the NPCs, and a secondary healer once he gets his healing song).
For IWD2, you have a different rule set, so be sure you're familiar with how it works. A party composition that I like for this game is:
1/2 Orc Fighter - pure Fighter all the way. He's your tank and melee specialist
Dwarf Fighter 1/Cleric X (I take the one Fighter level for an extra feat and for proficiencies) He's your healer/buffer/secondary tank
Elf Fighter/Rogue - this is your main Rogue who takes care of locks, traps, and scouting and he also takes Fighter for feats and Base Attack Bonus. He specializes in ranged weapons.
Aasimar Bard - because I love Bards and Aasimar get a boost to CHA.
Human Wizard - specialize this guy.
Human or Aasimar Sorcerer. This is the party 'face', whom you should load with Diplomacy and Bluff.
This group works great for me, although is by no means the optimal powergaming group.
