Elemental Meta-Traits
Variable
Your body is wholly composed of a particular substance. This is an entire category of meta-traits, one for each class of substance ("element").
The main use for these meta-traits is to create "elemental" creatures. Those who can switch into and out of elemental form – a common super-ability – should buy Alternate Form and take the relevant meta-trait as their alternate racial template.
