A Talisman of Arthas Moloch is a form of rare artefact found on the Dead World of Arthas Moloch by the forces of Commander Farsight. These hexagrammatic talismans were found hanging upon great robed statues during the T'au forces combat against Chaos Daemons on that world.
A Talisman of Arthas Moloch possesses strange properties that cause Warp-spawned creatures and psychic powers to falter before it. Whilst the Farsight Enclaves now possess several of these talismans and use them in battle, neither Commander Farsight nor his advisors have the faintest idea of how they work.
