When you are in an area where you can modify your equipment, you may allocate device points. To allocate them, select the item slot you want (Ranged, Special, Off-Hand) and select the item and it's level. For example: If you want the Rumbleblaster for the Robotics, you have 4 choices: MK I, MK II, MK III or MK IV. Choosing MK I will result in using 1 device point, while choosing MK IV will use 4 device points. Of course, this would mean you would have a stronger gun, but would take up more points. This means you must choose how you want to play: You could put more points into healing as Medic if you wanted to assist, or put them into poisoning, for a more offensive approach.
