Effect: The recipient of this spell is provided with
protection from normal extremes of cold or heat (depending on which
application is used).

He or she can stand unclothed in temperatures
as low as -30° F. or as high as 130° F. (depending on application) with
no ill effect. A temperature extreme beyond either of those limits will
cause 1 hit point of exposure damage per hour for every single degree
above or below those limits. (Without the benefit of protection such as
this, exposure damage is 1 hit point per turn for each degree of temperature.)
The spell will last for the prescribed duration, or until the recipient
is affected by any form of magical cold (including white dragon breath)
or magical heat. The cancellation of the spell will occur regardless
of which application was used and regardless of which type
of magical effect hits the character (e.g., endure cold will be cancelled
by magical heat or fire as well as by magical cold). The recipient of the
spell will not suffer damage from the magical heat or cold during the
round in which the spell is broken, but will be vulnerable to all such attacks
starting on the following round. The spell will be cancelled instantly
if either resist fire or [resist cold] is cast upon the recipient.
