I have never seen the "No Effect" message except against Cherufe.
Noisome Powder of DY is a bit more accurate but it's a -15% Atk down (and not -40%) for 1 min.
Right now Tidal Roar is the most reliable Attack Down debuff followed by Infernal Scythe I think, although it's hard to check for me since Tidal Roar overwrites it. (it's also the only BP that has a base duration of 1:30 for a maximum of 4:50 with 500 skill while Diamond Storm has a maximum duration of 6:20)
