So at about the time of this post, I was logged on to my Ferengi scientist.
I had bought the fleet science vessel retrofit (as you may remember from one of Voyager's encounters)
Here are screen shots of both my equipment build, and my skill points. Maybe you guys can tell me what helped me tank that cube in Khitomer elite just now
(please note, I didn't have ANY batteries when I withstood that cube's attacks)
