So for the final boss(the 2nd boss) in E-7. Unlock shortcut B--->D then what to do next until I can hear the "chime sound debuff"? I already unlocked the shortcut using fast STF fleet and I got one S-Rank in node Q with slow STF fleet. I'm on CASUAL MODE now. Do I have to gain AS in node C and node I in order to trigger the debuff?
