Champion Spawn Artifacts lists the new drops for champions

From UOGuide

This page deals with generic information concerning all forms of Bone Armor. See here for the specific Bone Armor item.

Bone Armor is the perfect get up for the evil inclined. Though somewhat aggravating to craft due to the requirement of bones in addition to leather, it's actually a fairly light-weight form of armor and offers above average resistances.

Base Properties

All types of armor in a given set come with the same basic resists. For example, a leather gorget provides exactly the same level of protection as a leather tunic. Armor that is exceptionally crafted will receive a bonus that is further boosted by your character's Arms Lore skill, while Runic Tools can be used to send the total resistance level far higher.

Some forms of armor are "medable", meaning they do not affect your use of the meditation skill when worn. Elven armor can only be worn elves.

Individual Properties

Bone armor is crafted by tailors. It cannot be recycled.

Parts retain the color of the material from which they are made. Crafted versions can have their durability increased, via Powder of Fortifying, to a maximum of 255 and can be dyed with Pigments of Tokuno. If crafted exceptionally by a GM+ crafter they can hold their maker's mark.
