Monsters

Breath Weapon (Su): A cone of cold 60x60x60 feet long, every 1d4 rounds; damage 11d6, Reflex half DC 33.

Frightful Presence (Ex): The dragon can unsettle foes with its mere presence whenever it attacks, charges, or flies overhead. Creatures with fewer than 33 Hit Dice (except for other dragons) within 330 feet of the dragon must succeed at a Will save (DC 29) to avoid this fear effect, and remain immune to that dragon's frightful presence for one day. On a failure, creatures with 4 or fewer HD become panicked for 4d6 rounds and those with 5 or more HD become shaken for 4d6 rounds.

Spells: Knows and casts arcane spells as a sorcerer of level 11, gaining bonus spells for a high Charisma score.

Spell-Like Abilities: 3/day-gust of wind, fog cloud, and wall of ice. These abilities are as the spells cast by a 11 level sorcerer (save DC 13 + spell level).

Freezing Fog (Sp): The dragon can use this ability three times per day. It is similar to a solid fog spell but also causes a rime of slippery ice to form on any surface the fog touches, creating the effect of a grease spell. The dragon is immune to the grease effect because of its icewalking ability.

Immunities (Ex): All dragons are immune to sleep and paralysis effects. All white dragons are also immune to cold.

Cold Subtype (Ex): Cold immunity, double damage from fire except on a successful save.

Icewalking (Ex): This ability works like the spider climb spell cast by a 11 level sorcerer, but the surfaces the dragon climbs must be icy. It is always in effect.

Blindsight (Ex): Can ascertain creatures by nonvisual means (mostly hearing and scent, but also by noticing vibration and other environmental clues) with a range of 330 feet.

Keen Senses (Ex): Sees four times as well a human in low-light conditions and twice as well in normal light. It also has darkvision with a range of 1100 feet.
