WaterbreathingThis may be a "wimp Power," but it would be embarrassing for an extremely powerful character to drown while a relatively wimpish water breather went unharmed.
When creating the character, the player can substitute any other breathing medium for water. This is often the case when creating an alien character, such as one who breathes liquid methane.
This power may be permanent or temporary. Characters with the permanent form have a decreased resistance to heat and aridity. A sauna might be a death trap. The hero is -1CS to resist and takes +1CS damage.
