Size Defensive Adjustment

Though large creatures are easier to hit, they are often far more difficult to damage due to the very size that makes them such large targets. For example, thought a dragon is easier to hit, it is harder to actually damage. For example, an archer’s arrows could, by the die roll, miss the dragon while the beast would literally be bristling with arrows that didn’t really do any damage.

The following size modifiers to defense replace the Size Modifier Table on p.134 in the PHB. All modifiers are added to or subtracted from the creature or character’s AC as appropriate.

Size Defense Modifiers

Size / Size Modifier
Colossal / +5
Gargantuan / +3
Huge / +1
Large / -1
Medium / 0
Small / -1
Tiny / +1
Diminutive / +3
Fine / +5

The seemingly out of place modifiers for both small and large creatures reflects that these creatures are not either large or small enough to benefit from being very big or very small. In fact, the grey area in which they reside carries with it a vulnerability that creatures who are either larger or smaller do not possess.

New and improved. ;)

Any thoughts?

Why would it be harder to hit a collossal creature than a medium one?
The phrase 'broad side of a barn' comes to mind

Though large creatures are easier to hit, they are often far more difficult to damage due to the very size that makes them such large targets. For example, though a dragon is easier to hit, it is harder to actually damage than a creature of only large size.

Your longsword is still pretty big to an ogre but pretty darn insignificant to a 100' long dragon. You are fighting the dragon with a weapon that will cause many, many little fleshwounds but very few really damaging blows. The ogre when struck will be far more likely to get something important cut in half, like his pancreas, killing him in short order.

My system reflects that very large creatures are rather easy to strike but far harder to cause damage upon.

Yes, but most large creatures already have lots of natural armor, and hit points. Also, it has the wierd side-effect of making big/small creatures of the same size harder to hit eachother, unless you make the table relative, which adds another step to calculating AC.
