It is a full page on size and the implications for the use of Growth and Shrinking.
not a lot of fluff so i'm not sure how much I should post
As shown in the Small Size Templates and in the Shrinking Power, being smaller than normal doesn’t automatically reduce a character’s STR, CON, PRE, defenses, BODY, STUN, or Running. The negative effects it has, as indicated in the mandatory Physical Complication, are being ⅛ mass, a halving of Reach, and suffering +6m of Knockback (distance only) per halving of height.
Therefore, in most cases, all that a level of Growth needs to do for a small character is double his height, double his Reach, and add -6m of Knockback Resistance. Since that’s all Growth provides, each level should only cost 3 Character Points. Once a small character reaches normal human size this way, if he wants to Grow further he has to buy normal Growth at the costs listed in the table on 6E1 229.
