Volatile Haze
Level 12 Blaster
XP 700

The ground is all but hidden beneath a blanket of mist, rolling and waving less than 2 feet from the floor. When activated, the mist takes on a sickly bluish hue, somewhere between the flicker of the lightning and the fading edges of an ugly bruise.

Hazard: A volatile haze occasionally forms in an area of high mystical energy concentration, such as a dragon’s lair. A faint haze in a 10-square burst, hanging at roughly calf level on a human, absorbs the energy given off by characters within it and then launches that energy back at those characters.
When the hazard is triggered, it takes on a crackling blue hue, and a ball of energy forms in the square at the center of the burst. An active haze does not change damage types with future attacks or spells; it retains its initial type until deactivated or until 24 hours pass.
A dragon fortunate enough to accumulate a volatile haze might wait until intruders have entered the haze and then breathe, knowing that the haze will continue to attack for it. Dragons even fi ght within the haze, counting on their own resistance to protect them.

If successful, that character takes half damage and immediately moves to the nearest untargeted square.
     A character can attack the ball of energy at the center of the haze, which has AC 23, Fortitude 23, Reflex 23, Will 23, and 87 hit points and is immune to the damage type it uses to attack. If destroyed, the haze makes a fi nal attack and then dies. It remains inert for 24 hours, after which time another energy attack can activate it.
