change my current inner ability?

Been meaning to ask this [sorry for hijacking this thread, but I'm a DS too so maybe it will be helpful]

Does Buff duration increase Blue Blood's duration [original lengeth 60 secs]. I've tried to test it out in alien pq with 19% buff duration, and for god knows reason I keep getting different numbers. I've gotten an increase in duration of 0 secs, 4 secs, 5 secs and even 10 secs. For reference, my infernal concussion always at 72 secs [12 sec extra due to 19% buff duration on 60 sec buff]

And are you sure that buff duration increases dark meta's time of being able to attack during damage reflect / physical def up? Was under the impression that it always stuck at the first 18 seconds of the skill activating the skill and cannot be modified by anything.

I'm not sure about blue blood, haven't tested it. I'm pretty sure it increases the duration of us being able to attack during reflect / cancel weapon attack though
