You can get it if you use the alternate feat from Arcane Power, but it ends once you've dealt curse damage.I do have a mild concern about the mechanics of supporting both multiclass and hybrid characters. For example, some features of the Underchasm Darkwatcher (warden and warlock as prereqs) require you to have Warlock's Curse, which I don't believe you have if you're a warden multiclassed into warlock.
Note that I don't necessarily consider this a flaw in the PP design, but I think the article should note such issues or clarify the designer's intent.
I, on the other hand, do. I don't want flavor-oriented players to shoot themselves in the foot just to squeeze a little use out of their PP.
