The XP cache was an item given to players who had played at least 10 hours of DarkScape prior to its closure announcement on 29 February 2016. It acted similar to a prismatic lamp; clicking on the item would bring up the skill selection interface, allowing you to obtain experience only on your chosen skills. The XP cache contained experience that was equal to half of each of your skills in DarkScape that had at least 20,000 experience. Skills that had experience below this number were greyed out in the interface.
