Horn of Blasting

Horn of Blasting: This magical horn appears to be a normal trumpet, but it radiates magic if a detect magic is cast upon it. It can be sounded as a normal horn, but if the correct word is spoken and the instrument is then played, it has the following effects, both of which happen at once:
# A cone of sound, 120 feet long and 30 feet wide at the end, issues forth from the horn. All within this area must roll a successful saving throw vs. spell. Those saving are stunned for one round and deafened for two. Those failing the saving throw sustain 1d10 points of damage, are stunned for two rounds, and deafened for four.
# A wave of ultrasonic sound 1 foot wide and 100 feet long issues from the horn. This causes a weakening of such materials as metal, stone, and wood. The weakening is equal in effect to the damage caused by a hit from a missile hurled by a large catapult. See "Siege Damage" in Chapter 9, and suffer an additional -2 penalty to the die roll described there.
If a horn of blasting is used magically more than once per day, there is a 10% cumulative chance that it will explode and inflict 5d10 points of damage upon the person sounding it.
There are no charges upon a horn, but the device is subject to stresses as noted above, and each time it is used to magical effect there is a 2% cumulative chance of the instrument self-destructing. In the latter case, no damage is inflicted on the character blowing it.
==Combat & Tactics==
