I believed that these where great weapons, maybe even greater than the Peiste Cesti, but then I went and tried them myself.
The effects hit very often yes, but I cant seem to notice them making that much of a difference in a fight.

I mean I can barely see any poison damage (if at all) and the paralyze effect although cool rarely works.
I am not sure if I have to build mage stats in order for the debuff effects to be noticable, but since I haven't these barely work.

I still like these weapons but not over Peiste, I wouldn't pay 1million for them since I can pay 50k and get Peiste +1.
