Big warning, nobody should use ONE HIT feature because previous one already detected by Devs and they planned to improved security by adding more detection against God Mode, 1-hit kill.
Abusing active skill is plausible right now, they will either ban or did not see it as long as you used them few times, not every seconds. Just try to play normally and Google version is really bad compared to Nutaku Version due they really hard to get operators (character) but One Hit feature was being freely used in there and still dont have ban report currently while in here ban wave coming faster right now.
