Well, those classes that have a bonus to a skill will show that bonus--so it may appear that you can increase their skill beyond 75. However, you can only increase the base level of any skill for any race or any class up to 75. Those class-based bonuses just make it look like you're increasing it beyond that point. Lords do not have a bonus to the sword skill--so you can only increase sword to 75 for any lord. Rogues have a bonus to lock & traps skill--so, no matter what the race, I can increase the rogues' lock and pick skill to the base level of 75--but I can't see the base skill level, I can only see the skill level with the bonus added--so it will LOOK like I'm boosting it well beyond 75.
