This item replaces the bronze neck guard. The means of acquisition have not changed:
Get the shards of a black metal blade from MT, give them to Dogmoch the blacksmith; he will give you some boots. Ask Hamilcar elephants, then go to the plateau wearing the boots. Ask Mazbuud the tamer elephants, and then give him the boots you're wearing.
Note: The boots is restricted to non-good alignment.
This probably mean the neck guard is also non-good just like the previous version.
