There are books that raise a skill by one.If you find a trainer you can't use, keep a note of it and the next time you respec, make visiting them a priority before you redistribute your skills Certain trainers can only train your skills at certain levels (I think you either need to have a skill of 0-3 for basic trainers, and 4-7 for advanced), and only once.The end of tree magic spells are pretty ridiculous (meteor & tempest), especially if you have plus to elemental damage gear.The faction side quests are generally better than the other side quests.A lot of folks recommend avoiding these skills because of those two things (breaking the game, removes the 'oh man look at how great this unique sword/whatever looks that I just looted' factor). Blacksmithing plus sagecrafting will break the game pretty easily, but will put you in generic looking super-armor.If you want any combat difficulty at all, play on hard.You can respec pretty much at will once you get a little bit into the game, so don't worry about screwing up your build.
