Ice dragons have pale blue-white skin, ranging from sky blue for a hatchling to the stark pure white of an ancient individual
Ice dragons have pale blue-white skin, ranging from sky blue for a hatchling to the stark pure white of an ancient individual. They are the same color all over, having no contrasting underbelly color.
They prefer to live in cold regions, whether in the highest mountains or in the cold northern lands. They are the least intelligent of dragons, though this does not mean that they are stupid by any stretch of the imagination. They are motivated completely by a drive to live, to reproduce, and (of course) to accumulate treasure; they kill to live, not for pleasure.
In a fashion similar to swamp and desert dragons, an ice dragon will sometimes choose to bury itself in snow and wait, with only its eyes and nostrils exposed, in a place where prey is likely to pass by. The ice dragon will then burst out when likely prey approaches within 100', surprising on a roll of 1-4 on 1d6.
Ice dragons are immune to normal cold, and take only half damage from magical cold or ice.

A proud, ancient race of gigantic, carnivorous, winged reptiles. There are many subspecies of dragon, many of which are distinguished by the colour of their scales. All dragons are egg-layers and hoard treasure in their lairs, far from areas of human civilisation.

Found in cold regions
Almost the antithesis of the fiery red dragon is the frost-rimed white dragon of the frigid north. Although lesser than their red cousins in size, power and intelligence, they are at least as evil.
White dragons only rarely (20%) are known to speak, very rarely (5%) cast magic, but frequently (60%) will be found asleep. If the dragon is asleep, there is a 1 in 6 chance that it will awaken in the presence of adventurers. Dragons also sometimes feign sleep.
If a white dragon can cast spells, it will gain spells as a magic user of a level equal to one half of its age category. So, an ancient white dragon casts as a 4th level magic user.
