The Mask of Sliske, Shadow, also known as Shadow, is a sentient mask that is involved once more in the Dishonour among Thieves quest, where it is upgraded as a reward that allows it to toggle into a pocket slot item with a passive.

This upgrade gives the mask, when worn, a 1 in 30 chance in combat that a wight ranger will spawn and fight for you. The mask cannot be used with Dreadnips and the wights will not appear in PvP.

If you destroy the mask in its upgraded form, you can still reclaim it at the Statue of Death, but you will need to re-buy the upgraded from Moia for 10,000 coins, after the Dishonour among Thieves quest.

The mask can also be worn in the head slot, thus saving space for a scrimshaw being worn. To do this, right-click on the upgraded version of the mask and click Switch. This will give you the option to `Switch to mask`. Returning the mask works vise versa, Selecting the `Switch to pocket slot` option.
