Horn of Collapsing: The horn appears to be a normal musical instrument,
perhaps a bugle or warning horn of some sort. If it is sounded without first
speaking the proper rune<default font for rune>, or 10% of the time in any event, the following
will result:

    Outside: A rain of fist-sized rocks will strike the individual sounding the
    horn, from 2-12 in number, each causing 1-6 hit points of damage.

    Indoors: The ceiling overhead will collapse when the device is blown,
    so the character will take from 3-36 hit points of damage.

    Underground: The area immediately above the character sounding the
    horn will fall upon him or her. The damage is 5-20 hit points base,
    multiplied by 1 factor for each 10' of height from which the material
    above drops (i.e., twice damage if a 20' ceiling, three times damage if
    a 30' ceiling, etc.).

Proper use of a horn of collapsing enables the character to sound i t while it
is pointed at the roof overhead from 30 to 60' beyond the user. The effect
is to collapse a section of roof up to 20' wide and 20' long (10' radius from
the central aiming point) which inflicts damage as noted above if indoors
or underground only.
