Iceberg

Iceberg (minor) by Stone Gargoyle

The character generates excess moisture under his skin and freezes it. This makes him resistant to cold and heat attacks (half damage), gives him a Natural AR of 12, and provides him with an extra 20 SDC at level one, plus 2 SDC per level. The character is invisible to heat sensors and can go for his PE attribute number of days without water. This does, however, reduce PP and Spd to half while active. It is always on unless the character concentrates (losing one melee attack/action per round) to stop it temporarily (up to his PE attribute number in minutes) ans sweating off the excess moisture.
