GIGANTISM

Gene Pool -2 | Disguise DC Modifier +20

Your mutation has altered your physical size, and your size makes you noticeably different from others of your species. This mutation causes you to grow, doubling your height, multiplying your weight by 8, and  increasing your size category.  You gain 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 EAC and KAC.  If gigantism increases your size to Large you occupy a 10-ft. space and gain a natural reach of 10 feet. This mutation does not change your speed. 

You can no longer wear armor or use some types of equipment designed for Medium humanoid creatures.  Natural weapons and unarmed strikes deal more damage (see Table: Tiny/Large Damage).
