Size modifiers

[jun]

Support Issue: Basic Rules
The Issue: Is this creature size movement differences?

Fine: -8; Diminutive: -4; Tiny: -2; Small: -1; Medium: +0; Large: +1; Huge: +2; Gargantuan: +4; Colossal: +8; Titan: +16

Looking at Enlarged Form (augment) and Ancestry: Jotunn (trait) both makes movement count as large but I can't actually find creature size movement differences in the players handbook, but I did find this (quote) without an explanation of what it is for, in the section pertaining to size modifiers.

I would say, if Jotunn says it makes you the “large” creature size, that would include any outstanding bonuses that come with that size increases…I think? Who knows lol.
