Arctic Chill

Cooldown: 2.5 - 5 hours, varies by skill

Syntax: cast 'arctic chill'

By summoning forth the cold endemic to the frozen poles of the world, a mage may empower his chill workings for time. While this effect is present, all cold damage caused by the caster will be slightly higher. Furthermore, the power of his frostblast spell will be much enhanced, and when he casts iceshard he may find it turned into a spray of multiple such shards. However, all spells will cost additional mana from the need to draw upon such cold; as this is more difficult in warmer climes, so too will the mana cost be higher in warmer temperature, and substantially so in very hot weather.
