To everyone arguing the rules of D&D:

You all have made one fatal flaw when it comes to the rules of the game, and it is contained in both the DMG and the PHB, which is that ultimately, the run-down of the game is decided by the DUNGEON MASTER, and that any rule that the [DM] does not agree with in the game can be house-ruled out.
So therefore, any additional rules that come from any of the supplemental rulebooks don't mean squat if your [DM] doesn't use them.

Sorry if that's harsh, but, Jesus, the rules of D&D are as subjective as the alignments of its characters. Any [DM] worth his/her salt knows that.
