Using the scrolls you may get from  Hermit Ortell, you can create an Object of Beckoning, which allows you to choose which Elemental to summon at a Wind stone in Silithus.

There are various reasons why you would want to decide on which Elemental will appear. For example, as part of your Dungeon Set 2 quest, you will need to summon "The Duke of Cynders", which is a Fire Elemental that can spawn at a medium wind stone, and it might be very time and money consuming to make him spawn if you're unlucky. Another reason is the immunity of fire elementals to fire and water elementals to water spells.

Objects of Beckoning come in three sizes: Crests (Lesser wind stones), Signets (Medium wind stones) and Scepters (Greater wind stones). They can only be used once.

Summoning the Elemental destroys one associated Object of Beckoning, just like the Twilight trappings are consumed by each summon.
