Dome of Extreme Weather

You choose a zone that you can see within 150ft., (a 50ft. dome) any creature inside this zone will see and feel as if in a Extreme condition of Cold (Frostbite, Snowstorm, hailstorm, slash of cold winds, etc...) or Heat (Massacrating heat, desert, the water of canteens will evaporate,etc...), you can move the dome as long as the chosen center is within sight and range.

From outside there is nothing happening to the affected by the spell.

when cast at higher levels, the size of the dome grows by 25ft. per spell slot level.

The dome will only dispell when a dispell magic is cast, if an anti-magic field is cast within the dome, the illusions will not work.
