Pieces of this set are considered "rare" and should spawn only from Peerlesses, bosses in the Doom Gauntlet, named Mondain's Legacy monsters, and certain event specific monsters such as the ethereal forms of the Shadowlords.
There is some mystery surrounding which parts can be acquired from which creatures. Some players have found that only certain parts will drop from non-Peerless/Darkfather monsters, while other players claim to have received all parts from standard "named" monsters. It may be that some named monsters will not drop certain parts from certain sets. However, due to their immense rarity, it is difficult to determine any exact patterns with certainty.

- Self Repair: 3 (per part)
- Swing Speed Increase: 30
- Hit Chance Increase: 15
