Material

A material spell allows the magic-user to actually bring into being certain common things. 

There is no great difficulty in causing common basic materials such as stone, earth (soil), or wood to appear. These sorts of materials in raw, unworked form are easily gained by means of this spell. Similarly, other inorganic or non-living materials such as water, air, dung, straw, etc., can be conjured.

When simple plants are concerned, such as when the caster attempts to bring into being an area of grass, there is a base 100% chance of total failure, modified downward by 1% per level of the spell caster.

Animal life can never be affected by this spell. In no event can worked, refined, or fabricated items be brought into being by a material spell, nor can rough gems or precious metals. 

The spell essentially enables the magic-user to create common things of a basic nature.
