I need to know which stats to put out for a solo Assassin-Mage, Assassin-Sorcerer, Kensai-Sorcerer, Kensai(BIG CHALLENGE), and Assassin-Fighter. Thankings are in ordering....I guess....

I don't think Assasin->Sorceror and Kensai->Sorceror is valid. Solo characters always need a lot of juice. Prepare to roll for some time.
Strength - 18 (essential):
You need a lot of strength because you need to haul everything by yourself. If you are not playing BGT you may face problems with the non-warrior types because you cannot get 19. Rely on belts then. Ass->Mage cannot use Crom Faer either.
Dexterity - 18 (essential):
Especially for the kensai types who will have to cope with very high AC. Contributes to missile TH and thieves skills as well where applicable.
Constitution - 15/16/18 (essential):
15 if you play BGT and non-warrior. 16 if you play SoA and non-warrior. 18 if you play warrior.
Intelligence - 3/18 (essential to some):
Only essential to mage duals. Very essential in that case.
Wisdom - 3 (redundant):
Something has to go. In this case Wisdom. Make sure to purchase a few potions of insight and drink them when you cast Wish-type spells.
Charisma - 3 (redundant):
4 words. Ring of Human Influence. Just slip it on in non-combat zones (which usually happen to be negotiation zones) and you will be dandy.

To put it in plain language - sacrifice Charisma first and Wisdom second. Don't accept less than optimum in everything else.

If you don't want to keep wisdom quite so low, or don't feel like rolling for hours, you can leave strength at 12 or so. Before very long, you'll be able to buy the girdle of hill giant strength at the Adventurer's Mart. You can do the same with Dexterity, but you have to do a fairly extensive quest to get said item.

Look at FAQ sticky thread about dual classing.

Dualling to a kit is invalid. Therefore you may not dual to a sorcerer.

You cannot dual to a sorceror because it's an invalid multi-class, not because it's a kit.
Sorceror->Thief is also impossible.

I wouldn't really enjoy playing a character with any stat under 7. I mean, wisdom of 3 would make you, well, Neeber. Do you WANT to be Neeber? Charisma of 3, well, means your char has leprosy. Would you want to be Neeber with leprosy?

You can get your strength high with many items, your dexterity high with gauntlets. 18 Constitution would be good for part fighters, 16 otherwise. 18 intelligence would be good for part mages. Otherwise, you probably won't even notice the difference. (Oh, for part thieves, 18 dexterity would be useful and in-character)

I'll just touch on the Assassin->Fighter.

STR of 17 needed.
DEX of 15 needed.

WIS & INT 10.

CON of 16.

CHA of 12.

That will be only 70 points. [img]smile.gif[/img] If you intend to fully powergame however, then max out CON and DEX to 18. Now it is a total of 75 points. Whatever excess points you have, put in INT.

80 points if WIS & INT are 10 each . . .

Well, can you dual to a sorcerer? Or dual anything from a sorcerer? Then I would one happy Bhaalspawn.

And could you use SK to have a multi-class Assassin-Sorc or Kensai-Sorc?
