Artifact Weapons are weapons which are strong and infused with abilities which set them apart from the standard affair of weapons, but are not quite to the point of being Legendary weapons. They have a price, can be purchased, and are not one-of-a-kind even if their presence is exceedingly rare.
Beastbane
This weapon uses the stats for a longsword, except as follows; the Beastbane deals an additional 1 point of damage (bypassing Soak) when hitting creatures of the Animal type. In addition to this, Parry attempts against Animals receive a +1k0 to the roll. Beastbane costs 8,000 Gold.
Centurion's Lance
This weapon uses the stats for a lance, except as follows; the Centurion's Lance also possesses the Brutish and Switch properties. While in its one-handed state, it possesses Finesse instead of Brutish. As a full-round action an attack can be made with the Centurion's Lance in a 2 square line, dealing half damage on a miss. Centruion's Lances cost 12,500 Gold.
