The adamant berserker shield is a reward that can be purchased with tokens from the Fist of Guthix minigame. It degrades with use like barrows equipment. The shield can only be traded when it is completely uncharged. Reggie in the Fist of Guthix lobby can recharge the shield for 10 Fist of Guthix tokens. A level of 45 Defence is required to wield it.
- The uncharged version used to miss few spikes before, now looking identical to charged version. It is most likely a bug that is yet to be fixed.
