This weapon was used by the legendary Saradominist Ivandis Seergaze, who helped in an assault against Lord Drakan. The original rod, wielded by Ivandis Seergaze himself, can be found sealed onto the lid of his coffin.
Before the EoC, It was possible to forget to have a sapphire in your inventory, and still make an item called a Silvthrill rod. The sapphire could not be added afterwards, and the rod would have no use.
Before the Evolution of Combat, this weapon used to have a special attack called Retainer. It would freeze a Vampyre juvinate which had less than 1/2 of its health remaining. Each use of the special attack would use up a charge. Once all 10 charges had been used, the Rod of ivandis disintegrated into Rod dust. This dust is now a discontinued item and has no known use.
Rods with less than 10 charges are discontinued items, as charges can no longer be used.
Once the Rod of Ivandis has 2 charges remaining, the Examine text changes to become "2! 2 charges left! Ha Ha Ha." This is most likely a reference to Count von Count of Sesame Street .
