The best way to farm Sealed clue scroll (elite) in large numbers is using 5 Manifest shadow in a Personal slayer dungeon. This method requires level 99 Slayer and also the captured souls of manifest shadows. Alternatively, if the player doesn't wish to spend the time capturing souls there are a variety of online resources that are dedicated to the sharing of other players dungeons that have the required souls within.
This method gives, on average, 3-5 clues per hour.
To farm Manifest shadows the player must have high combat skills and high level combat equipment. This method can also be almost lossless in regard to GP expenditure however a loss is to be expected some times.

The player should use Protect from Melee and Turmoil at all times. If the player is able to use the Penance aura they will not require any form of prayer restore. Since the primary focus of this method is clue scrolls, a luck enhancing ring should be used at all times. It is highly recommended that the player uses augmented equipment, Enhanced devotion is very helpful and will make this method almost entirely safe.
A legendary pet can be of use to make this method more AFK but is not required.
