With a touch, you change the state of the object touched, to solid, liquid or gas. You can affect material up to a cubic meter per level.

The state change is permanent, in terms of the magical effect, but if the material cannot remain in that state under current circumstances, it will revert. The speed of this reversion varies according to what was affected. Turning liquid water into ice will require some time to melt, whereas turning rock into lava will result in it cooling very, very quickly. Turning rock or metal into vapour in a normal environment will cause it to sublimate back very quickly, resulting in the rock or metal essentially becoming powder. The Director is the final arbiter of how long the material will remain in its altered state.

The magic of this state change is such that the material will not gain or lose heat as a result of being changed to its altered state, and will also gain or lose no heat as a result of changing back over time. Because of this, you cannot use this spell to create ice to chill your drink, but you also cannot use it to create a thermobaric explosion!
