General Method Description

Asyn remains are used in the Shades of Mort'ton minigame. Cremating them using pyre logs gives gold and keys that can be used to get rewards from the chests in the shade tombs. Different shades occupy various areas of the tombs, with asyn shades the second highest type (combat level 100). Since players like the Firemaking XP and Prayer XP from cremating, as well as the rewards, the remains dropped by high-level shades sell for a good amount on the Grand Exchange. Fighting them can thus be a good moneymaker, as well as being a nice way of training combat stats. Note that you should always use a Salve amulet(e) for these, as they are undead.

To access the asyn shades you will need a black or silver shade key. To get one, purchase a couple of asyn remains yourself and then pyre them until you get a key (the remains are tradeable but the keys are not.)

At level 96 Summoning, the pack yak lets you collect a large number of remains on each trip, improving your efficiency considerably.
