Swordmages (and hybrid swordmages) get Intelligent Blademaster as a bonus feat at level 1.
Reasoning: Mostly the same reasoning as giving monks a basic attack.
Backgrounds that modify which ability score your HP is based off of are banned. In addition, the following FR backgrounds have been been modified:
You gain one additional language of your choice, and you gain a +5 bonus to knowledge checks made concerning demons.
You add Bluff to your list of class skills, and gain a +2 bonus to Bluff checks. In addition, you gain Thayan as an additional language.
Reasoning: I have always disliked the background benefit of using another ability score rather than Constitution for your hit points, largely because it's so much better than any other background benefit for a class that isn't based on Constitution. In addition, it can result in a striker having as much HP as a defender without investing anything in improving their hit point total (other than the Background slot, but we already established that it was by far better than the other options). So, sorry, but I'm changing this and confirming my stance.
Knowing an enemy's resistances and vulnerabilities is now part of the information you receive by meeting the moderate DC for the creature in question. Knowing information about their powers is now part of the information you receive for meeting the hard DC for the creature in question.
In addition, you may need a different knowledge skill to know some of the monster's powers than to learn more general information about them. For example, a creature with the natural origin that invokes the power of Orcus will reveal basic information and its natural abilities via a Nature check, but understanding the divine power it uses will require a Religion check (hard DC).
Reasoning: It was kind of weird that you could learn so much about a monster with a largely unrelated skill, purely because of its origin. It doesn't make much sense to know about an arcane spellcaster's abilities via a high nature check just because it happens to be an orc. Additionally, it seems to me that a monster's resistance and vulnerabilities should be more common knowledge than its exact powers.
