yeah I know, I recently put on foul waters to lower str of the new skirmish enemies, also the DOT helps on the behemoth when it level ups, I tried to stick sound blast, cold wave, and foul waters on the Nm to help, but every time I apply foul waters , cold waves frost effect comes off, and vice versa, I made this into a faq 2 days ago, in hopes that they would correct this as well as take a look at the spell description...... they asked me to submit a bug faq, and then SE locked the forum....... it didn't make too much sense to me because I know this isn't the first time its been brought to their attention, and they were requesting too much... it puzzled me, just like how the frost and drown effect not stacking is puzzling ; ;
