The demonic sigil mould is used to make Demonic sigils, which are used in the Shadow of the Storm. Players may obtain a sigil mould from Jennifer, a disciple of Denath, who can be found in the demonic throne room under the Ruins of Uzer. To make a Demonic sigil, players must have 30 crafting and use a silver bar on a furnace whilst having a sigil mould in their inventory. The sigil is used to defeat Agrith-Naar the demon. After completing Shadow of the Storm, this item will no longer function: attempts to make a sigil with it will trigger the response, "There is no need to make another sigil now you have defeated Agrith-Naar."
