I made a character using the race builder and spent the points required to be large. During a comment conversation it was pointed out to me that I might be doing something wrong here (besides that you shouldn't be having conversations in comments).
Large (7 RP): Prerequisite: Humanoids taking this quality must have the giant subtype; Benefit: Large creatures gain a +2 size bonus to Strength and a –2 size penalty to Dexterity. Large races take a –1 size penalty to their AC, a –1 size penalty on attack rolls, a +1 bonus on combat maneuver checks and to their CMD, and a –4 size penalty on Stealth checks. A Large creature takes up a space that is 10 feet by 10 feet and has a reach of 5 feet.
Since enlarge person has similar wording
The target gains a +2 size bonus to Strength, a -2 size penalty to Dexterity (to a minimum of 1), and a -1 penalty on attack rolls and AC due to its increased size.
Then there is mythic enlarge
If the target grows two sizes, its weight increases by a factor of 25, it gains a +4 size bonus to Strength, and takes a –4 size penalty to Dexterity and a –2 penalty on attack rolls and to AC because of its increased size.
Now mythic seems to suggest that there is a relation between size and having a bonus to str and penality to dex, but looking at stuff I cant actually find this as a fact. So does that mean the +2 size bonus I have from naturally being large does not become +4 when I become huge, it simply stays as +2? What about the dex, does it stay at -2 or become -4?
