How long is this skill's duration?

[Cahaun]

I've been using the Curse skill on my sorcerer, and I was wondering how long the debuffs last on the mobs. There is no description that states how long they are active.

Eh I don't know about that, but you could go to Brackenridge and test it I guess? Or maybe in Watcher's or Kraag Tombs? I don't know because I don't have that skill! Sorry:/

The thing with this skill is that the mobs don't show any appearance of being cursed.

Oh! Well then I don't know what to say:/

For this exact reason I did not choose this skill. It never says how long it lasts. Could be as short as a few seconds which to me makes it useless.
