Glass sword

The Glass Sword is a one-handed sword, and a very mighty magical weapon, capable of killing every enemy with one, single strike. However, the very nature of this sword is also its greatest disadvantage. After the glass broke, and the magic killed the enemy, the sword is useless and can only be thrown away. Therefore, adventurers keep them for especially dangerous foes. Due to their nature, Glass Swords are light in weight.

History
Glass Swords first appear in Ultima V, in the spot in Serpent's Spine, where in Ultima IV the White Stone was found. Up to six of them the party can posess, but they will only reappear at this very spot after the old swords are being used up.

In Ultima VI, Glass Swords can be found as loot, or are made by a glassmaker in Minoc, who demands Peer Gems and money for his work. One Glass Sword is needed to make one of the Lenses.

In Ultima VII and VII/2, the Glass Sword is a rare loot. But Pothos in Moonshade sells them too, demanding 1500 Guilders for each sword. The Avatar's Glass Sword is in posession of Hazzard the Trapper.

In Ultima IX, Glass Swords also only can be found. But they have lost some power (some enemies survive one stike now)
