Another weapon for this purpose could be the Flail of Ages +5. Furthermore, the weapon deals 1d10 +4 points of piercing damage, weighs 12 lbs, has a -4 THAC0 bonus and a speed factor of 5.
Trying to profit from the strength of greater beings, many years ago the mage Ullion founded a dragon-worshipping cult under the moniker "Son of Drago." Attracting followers with promises of conquest, he sought to secure his authority by enchanting this symbolic weapon for his bodyguard, Jaramor Bold. When the Dragon's Breath strikes an opponent it releases the harsh flames of a red dragon, the poisonous vapor of the green dragon, the blue dragon's lightning bolt, a spray of a black dragon's acid, and the white dragon's penetrating cold. Unfortunately, Ullion was the first to feel its effects, slain by the ambitious Jaramor who sought to rule. There was no real power to be had without the mage, so the entire organization soon collapsed on itself.
