I played and finished IWD:EE this whole year and I am feeling like it is time to try the expansion: Heart of Winter (HoW). This time, I want to play with characters I do not usually play with. The main game was too easy and my party members reached 1.5 Million experience each so I do not want to use them and make the HoW easy too (HoW starts with 500K exp characters). Here, I'll share my planned party and ask a few questions for anyone who is willing to share their opinion.

Update: Created all characters with 100 rolls per character and choosing the best ones.

--------------------------------------------------------

* I tried to distribute weapons to my characters so if I find a good weapon, one of them will surely use it.
* I tried to have all 6 non-evil alignments.
* I tried to have Human, Elf, Half-elf, and Half-orc
* I do not want a Cleric in my party. Nor Paladin.

Questions:
1. What does Charisma do for Bards? Do I have to set it to 18? If not, I am thinking about making Dragon disciple party leader.
2. For Dragon Disciple, should I choose a human to receive 20 CON? (DD gets 2 bonus CON)
3. What does Charisma do for Druids? Why is it 15 minimum?
4. What does Wisdom do for Monks?
5. Does "Single weapon style benefit" apply to fists/unarmed? (+1 AC and critical at D19)
6. What is the population of undead in HoW? I am thinking about selecting spectral undead as Racial Enemy for my Archer. In other words, what is the hardest race to kill with arrows?
7. I noticed that when I start a new game with new characters, my characters are all naked. Will that be a problem? I'll certainly miss my bag of arrows and bag of holding.

If you have any further suggestions, please feel free to share.

Tnx
Engin.

EDIT: Updated my party.

With stats like that it's no wonder the game was too easy. Wow, talk about overpowered. NPC reactions and shop prices. No need for 18. So long as you don't go below 10 you won't be penalised in any way. Only if you're intent on power gaming. There's no need. See above. In the computer game (as opposed to P&P), nothing. Unarmed combat doesn't benefit from weapon styles. High. Skeletons have insane resistance to piercing damage. Why would it be a problem? Everybody is in the same boat.

Thanks a lot for the answers Hickory. You are amazing :)

The starts are merely a reference for me. When I create a character, I give myself 100 tries and pick the best one.

About inventory, thanks a lot. If you start the game with the default characters, they have some nice items. Same thing happens when you start the game with your Original game party. It is good to hear that that's not going to be a problem.
