Spells (3e)

The character creates an unmoving, opaque sphere of force of any color the character desires around him or herself. Half of the sphere projects above the ground, and the lower hemisphere passes through the ground. Up to nine other Medium-size creatures can fit into the field with the character; they can freely pass into and out of the hut without harming it. However, if the character removes him or herself from the hut, the spell ends.

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-degree-for-1 basis (thus, if it’s –20° outside, inside it’ll be 50°). The hut also provides protection against the elements, such as rain, dust, and sandstorms. The hut withstands any wind of less than hurricane force, but a hurricane (75+ mph wind speed) or greater force destroys it.

The interior of the hut is a hemisphere. The character 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 (they have total concealment).
