This skill allows absorption of scrap produced by destroyed ships and structures with which to repair the Orkulus. Upon activation, scrap will be drawn from around the Orkulus, restoring Antimatter and hull points.
Keep in mind that the game seems to only see scrap without caring what it was originally part of, so parts from a scuttled Jikara Navigator will be regarded the same way a destroyed one would. This is would be very useful against Titans or large groups of frigates/cruisers because they produce a lot of scrap, but would be less productive with capital ships.
