VV's first post on the rules crazymonkey uses for making gods was posted
here
It seems to state that for every point you put into a size increase you get +4STR -2DEX and +2 CON, and these are not cumulative like in the MM. The chart I found is for Improving Monsters (pg.291). There is no standard for the size of a monster and the bonus to stats I can find, stat increases are all done by race.
Example:
gargoyles get +4STR, +4DEX,+8CON,-4INT,-4CHA and are Medium size
hill giants get +14STR,-2DEX,+8Con,-4INT,-4CHA and are Large size
The PC's start out with no bonus to stats and can increase them and they can also increase their size and there by get the improvements to their stats as a bonus. Kind of like building your outsider race.
The chart was copy pasted from VV's post so I was wondering how their was a difference. But maybe it is the way it is listed. The Ability Score Increase is seperate from Monstrous Size but the benefits to stats is listed there.
Look at it like this you have two ways to increase stats and the second (Monstrous Size) gives you other benefits and penalties besides to your abilities. Hide checks, grappling, vertical reach, armor class, and attack rolls etc. But about the bonus they are as listed as is and I will clarifiy here.
Code:
Size STR DEX CON PT COST
Diminutive -6 +6 -- 3
Tiny -4 +4 -- 2
Small -2 +2 -- 1
Medium +0 +0 +0 0
Large +4 -2 +2 1
Huge +8 -4 +4 2
Gargantuan +12 -6 +6 3
Colossal +16 -8 +8 4
So I hope this helps you determine your starting size Theroc and Glasseye.
