@toschi2222: I think that is intentionally unexplained. It could be that they thought red was alone and wasn't expecting her bf to be there. The transistor is powerful and when he became the user when he was inadvertently stabbed, he used it to teleport to safety, since that was his last thought before impact.
First, put all the purge() into passive slots, as it slightly increases your damage.
Then you need three active functions:
Mask(): for that sick unmask bonus damage
This pulls your enemy in, debuffs, crushes for more debuff. Remember, void stacks 3 times, and gives -325% to armor!
Follow this up with one attack
Crash already does massive damage, void puts 1.5x on to that, and load not only makes it aoe, the size of your magnet void that you conveintly pulled all enemies into, but also increases damage by 1.1%. Have fun one shotting everything, although its not the best with all the limiters on, as shielded multiple cores that quick spawn mean having crash as your only attack(who doesn't run Jaunt()?) is bad. This will also one shot your clone, and you can jaunt away till stealth comes back up and never take damage in the challenges.
