Here we go, hope this will help....
Say, you have 6 points to use. This will told to you when click on the screen that shows the skills.
You may go through and read each character's skills. The ones that are open to you now will be shown.
You may then make your decision..let's say you want to be proficient with a sword, click on that skill..a little light comes on under that skill. To reach perfection in a skill I think it's 5 points in that skill. Then say, looking at the thief's skill, lockpick looks very interesting, so click on it(it should be open to you)..you have now used up 2 of the 6 points..And you want a little magic for the big skellies..go into Mage and click on a really nice sounding skill..oh, meteorite strike..something like that.Again, chose between what is open to you at this time.
Again, you have used another skill point. Now you have 3 left..you may spread them around or go back and see if you're able to up the skills you have chosen.
Some will depend on your level if you're able to.
If not, you can save your poins or pick another skill, like IDing, or repair..
Every time you level, you get xx amount of skill points and every 5th level you get a bonus skill point..might be 10th, long time since I played, and lousy memory, but you'll know.
Now that you have these skills, you are able to use them as you go about your duty of clearing up the place and finding out why the Mage is Mad.
For your special skill, there is a little icon, I think on the right side, near the middle, click it and watch your warrior..whirl and kick..very nice in the heat of combat.
Hope that garble helped, if not, email me and we'll get it!!
