Translucent mask
The translucent mask is a temporary artefact able to shield the wearer from notice. Donning it will cause guards and other organisation-owned denizens to ignore the wearer for five minutes. This effect fails if they perform any hostile actions of any kind. Each mask possesses three (3) charges and permanently decays afterwards.
A rare resilient version of this mask exists, once sold at auction at fabulously high price. It carried five (5) charges and reformed twenty-four (24) days after exhausting them.
