The Quartermaster in the south-eastern corner of the Tyras Camp sells the halberds. Any type of halberd will suffice, but a higher-tiered type is recommended for a faster kill. The Elf Camp can be accessed easily by heading all the way south of the Prifddinas lodestone, passing the guards, and heading west through the dense forest. The halberd which was bought at the Tyras Camp does not need to be used for the killing part, players could just buy a bronze halberd and use any weapon to kill the elf, as long as the last hit is dealt with a halberd. The crystal halberd and its attuned version do not work.
