What's with these Mods?

[Tequila Sunrise]

Why do Attack/AC mods follow that weird pattern +/-1, +/-2, +/-4 and +/-8? It'd be simpler to do a simple +/-1 or +/-2 per size catergory...

 

[Perun]

For each size category removed from Medium, the modifier doubles (or halves). I suspect that's because each size category itself is either double or one-half the height of the category that precedes it (Fine <6", Diminutive 6"-1', Tiny 1'-2', Small 2'-4', Medium 4'-8', Large 8'-16', Huge 16'-32', Gargantuan 32'-64', Colossal 64'+).

Lol, I thought this was a thread bashing the ENworld moderators.

Ha, I'm glad I wasn't the only one.

1/2/4/8 is a weird pattern?

 

[Tequila Sunrise]

A colossal creature has the same size relationship to a gargantuan than a large creature has to a medium, so why should the mod difference be greater? (Both doubled distance in all three dimensions, so both x8 mass)

Well just to play devil's advocate, let's say that I'm wrong...but then why are grapple mods a simple +/-4 per category?

Not weird in and of itself, but weird in the context of size modifiers because it contradicts the precedent set by other mod progressions like grapple. It's not that I find it complicated; irregularities like this one just irk me.

Well, a blanket +4 to hit/+4 to AC would add a ton of appeal to playing gnomes and halflings.....

I wasn't suggesting that it would be better to use the exact grapple mod progression for attack/AC also, I only mentioned grapple because that progression is constant rather than exponential.

 

[cmanos]

it's called a geometric progression and it has been around since the time of the ancient greeks. No 'wierd' progression here. You double the bonus as you increase size categories.

Would you rather have an exponentioal progression?
