Dante, I know it sounds cool to have a dragon with 30 heads breath for 30x damage. Is that fair, game wise? Is it even sane? Unless you really want Multi-headed to be the end-all-beat-all template, I do suggest you cut damage from breath attacks by the number of heads.
An example: In the Draconomicon 3.5E, there is a monster called the Pyroclastic Dragon. All you need to know about it for the sake of this example is that one of it's breathweapons is a Disintegration Beam. (A line of Save-or-Die) Now, by the rules as best I know, there really isn't any defense against this perticular kind of attack. (Not technically a 'death effect' so Death Ward doesn't apply, and asside from a DM houseruling that the Proof Against Transmutation property from the Players Guid to Faerun is applicable, this attack is indeed unstoppable by anything less than a god)
Now, what would happen if I added, say, 30 heads to this dragon? Hm? By the Math, it should only be ~30 levels higher, right? CR ~55? Doesn't sound bad? 40~ HD, lots of bite attacks?. About as strong as a Hecatonchieres? Well, I can tell you that CR 55 is wrong. It's probably closer to 550! This monster can force 31 saves VS Auto-death on a single character (or even a group of characters) each 1d4+1 rounds. (Less if it takes some of the oh-so-fun feats in the Draconomicon) The odds of rolling a '1' are quite high.
So it doesn't matter if you are Thor, Darth Vader, Gandalf, or King Arthur, If you are caught in it's breath weapons and have the misfortune of being made of matter, you will die.
On to Virtual Sizes: Once a character can gain 45 HD from the free HD gained from virtual size, the system spirals out of control. (45 HD = 15 feats = +15 strength) Gaining 45 HD from that table is not difficult.
