he is talking abt the 3 cores that you need to burn before 2nd and 3rd boss
specially the one that is in the open, 2nd core i think, has a button behinf the datacore but I have never been able to use it, tried it midcombat, tried going to it in stealth, tried everything, does not work, might be a NiM mechanic thing,.
^ This. Supposedly, from what Ive heard, is that if you Cloak out of combat and dont get hit by the cores discharges of electricity you can hit the switch and bypass the pull. Did it once but nothing happened so no clue what it should do lol
