Casting Time: 3
Area of Effect: 15-ft.-diameter sphere
Saving Throw: None

 When this spell is cast, the wizard creates an unmoving, opaque sphere of force of any desired color around his person. Half of the sphere projects above the ground, and the lower hemisphere passes through the ground. Up to seven other man-sized creatures can fit into the field with its creator; they can freely pass into and out of the hut without harming it. However, if the spellcaster removes himself from the hut, the spell dissipates.
 The temperature inside the hut is 70  F., if the exterior temperature is between 0  and 100  F. An exterior temperature below 0  or above 100  lowers or raises, respectively, the interior temperature on a 1 -for-1  basis. The tiny hut also provides protection against the elements, such as rain, dust, sandstorms, and the like. The hut can withstand any wind of less than hurricane force without being harmed, but wind force greater than that destroys it.
 The interior of the hut is a hemisphere; the spellcaster can illuminate it dimly upon command, or extinguish the light as desired. Note that although the force field is opaque from the outside, it is transparent from within. Missiles, weapons, and most spell effects can pass through the hut without affecting it, although the occupants cannot be seen from outside the hut. The hut can be dispelled.
 The material component for this spell is a small crystal bead that shatters when the spell duration expires or the hut is dispelled.
