The Adamant kiteshield (g) can be obtained as rewards from Level 2 Treasure trails, but can be used by non-members. It cannot be made through the Smithing skill. The gold design on it is purely cosmetic and has the same defence bonuses as the Adamant kiteshield. It requires 40 defence to wear.
Armour cannot be trimmed by players. Anyone offering to do so should be reported for Item Scamming.
