|Examine||A scroll for a karamthulhu overlord familiar.|
The Doomsphere scroll enables the use of the Doomsphere special move for the Karam. overlord familiar. Doomsphere scrolls are made by using Karam. overlord pouches on a Summoning obelisk, providing 0.1 Summoning experience and 10 Doomsphere scrolls. If the Voice of Seren is active in the Amlodd District in Prifddinas, using the Prifddinas obelisk will give 12 scrolls per pouch.
A maximum of 500 scrolls can be used on a karamthulhu overlord familiar to both store the scrolls and allow the familiar to automatically use the scrolls. They can be obtained again by clicking "Take BoB" in the summoning interface. They can also be added to enchanted headgear for a similar effect. However, fewer scrolls can be stored in them.
|Pouch to scrolls|
