Been thinking of playing this again....

Before i do, i would like to know advice and or where to find top builds for completing the campaign?

Before, whenever i look up builds.... i only find builds for something called 'battle of the builds'. There is never any mention of the campaign.

I dont think such thing as best builds exist for NWN games. Always you can use the "recommend" button while creating a character and see the prime attributes for classes. Also, there are 10+ classes so it mostly depend what kind of character you want to play.

You can find some helpful advises for classes here

Tell us what kind of player you want to play. A mage? warrior? rogue? Healer?
.. or a mixture of all like my favorite Druid which can cast spells, heal allies and is a solid fighter. The Animal compaion is an awesome bonus. A bard can sit back and play his/her songs and change the tide of the battle.

Enjoy the game.

The "recommended" button tends to give pretty haphazard advice. Sometimes its recommendations are downright terrible, to the point at which you have to wonder what the guy who wrote that logic was thinking. Anyways, NWN2 is much more forgiving than NWN1 since you will have a full party of NPC's at your disposal to help you out and cover for any weaknesses in your character. NWN2 tends to be a bit more forgiving than NWN1 in terms of character building because you have a party of competent allies to help you out. If you have a specific concept or preferred game style we can give specific suggestions, but for the most part you should be fine.

A few rule of thumbs for character building:

* Ensure your primary attribute is 16 or higher. If you're a melee fighter, that means you want at least 16 strength. If you're a Cleric, you want at least 16 wisdom. Archers want 16 dexterity, Bards want 16 charisma. Wizards/Sorcerers are a special case, and you really want that maxed out 18 in intelligence/charisma. At high levels it's basically the only attribute that matters to them, and points spent anywhere else are wasted.
* Make sure you consider how your character is going to contribute to combat and focus on getting abilities that synergize with that. It doesn't have to be damage (buffing and debuffing is very effective with the larger NWN2 parties) but make sure you're not dead weight.
* If you're playing a spontaneous spellcaster like a Sorcerer or Bard or Favored Soul, make sure to focus on taking a versatile selection of spells. A common beginner mistake is taking way too many hit point damage spells; you really only need one per level tops.
* At low levels, two-handed melee weapons are the best weapon class. Nothing else even compares. At higher levels other combat styles start to catch up, but a big hulking two-handed weapon remains the most reliable standby from start to finish.

Are you sure about that? I just checked recommendations for every starting class and they seemed pretty good to me. Ofcourse they are not perfect since it tried to make all stats above 10 and never makes the prime attributes 18 but it gives a solid general idea. I think it is always a good idea to press recommend first and then adjust settings after that so you dont accidently have 18 intelligence for Sorcerer instead of Charisma.

I've seen some absolutely puzzling suggestions for feats and spells, and the skill selection is generally nonsensical. Attributes are the hardest thing to screw up (put a high number if your primary stat and decent numbers in secondary stats) so it's probably the safest recommend button. I'd avoid it entirely everywhere else, though.

I prefer to play a ranged character, so possibly wizard is the way to go? Then party members can all be warriors and one thief?

I tried cleric before, its pretty good in general but lacks that extra potency for the tough battles.

What confuses me is multiclassing.

If i understand it correctly multiclassing is less powerful at lower levels but more powerful at higher levels, is that rite?

Wizards and Sorcerers work great. Max out your casting stat (intelligence for wizards, charisma for sorcerers) put a balance of points into dexterity and constitution, and you're good to go. The spellcasting prodigy feat is a great pick at 1st level. Clerics are a really powerful class. While their spells aren't as good as wizard/sorcerer, they're decent in melee and when bolstered by their own buffing spells are easily a match for the warriors-types in the party... while still being full spellcasters. If you want glass cannon full spellcasting power then wizard/sorcerer is the way to go, but if you want melee combat on the side Cleric delivers excellently. This totally depends on what you're doing. Some multi-class combos are great at low levels, some only mature at very high levels, and some are just plain terrible no matter what your level is. Rogue/Fighter is one of my favorite multi-class combos. It's easy to build and very good at what it does from the word "go". If you're planning on being a Wizard or Sorcerer, my advice is not to multiclass at all. It's really easy to screw up multiclass spellcasters and end up with a gimped character.

With that said, a few of the prestige classes are quite nice. Arcane Scholar of Candlekeep is a good one to aim for.

Rogue fighter sounds great.... I would only do the multiclass wizard if i had an exact build plan to follow.... where might i find those? But exact build pans are what i am looking for regardless..... its a nice feeling to know my character is optimized and i am not thinking about all the things i will do differently next game and loosing interest in my current game.

Thanks for that, however its not clear if all these builds are for the campaign or just in general? How do i know?

Single-class Wizard and multiclass Rogue/Fighter are very easy to build. I'll whip off some 1-20 builds off the top of my head for you:

Wow, thanks for that....

i have been reading on that website Olnortan posted...... i found a build i like; Celestial Dwarf King - Pal(6), F(4), DD(10), DC(10)
http://nwn2.wikia.com/wiki/Celestial_Dwarf_King_-_Pal%286%29,_F%284%29,_DD%2810%29,_DC%2810%29

I like that it is very tough and he mentioned its good for the campaigns.... that's exactly what i like! What do you guys think?

I hate paladins because all 6 Abilities are important for them. Maybe not intelligence.

Wisdom is only important if you actually care about spellcasting, which is irrelevant to multiclass Paladins, and dexterity is only important at low levels. At higher levels you'll be wearing full plate anyways, so 8 dexterity with a +4 dexterity item will cap out your benefits anyways. But yes, the Paladin and Monk suffer from being spread too thin and having to make serious sacrifices to make enfd meet.

One of my favorite playthroughs was as a fallen Paladin. Started off with Paladin levels, fell to evil and started the path of the Blackguard, then finished up as a Cleric (used the Aasimar for obvious reasons). Thanks to the Water domain I had evasion, and with Paladin/Blackguard I got charisma to saving throws twice for stupidly high saves.
