Multiclassed Warlock and cursing damage

[killswitch]

Hello all.

I am working on building a blackguard/fighter hybrid, and to get extra damage output, I'm thinking of taking Student of Malediction to give me a Warlock's Curse. I have a couple questions surrounding this though...

Using the feat Twofold Curse, I assume using the one encounter power will curse both, but this is only really beneficial if I use a close attack to be able to attack both of them.

Same thing for the epic feat Contagious Curse - however, with this one, am I even able to do it, as it say's I can use my warlock's curse on everyone, but I already used my encounter power for it...so I'm confused.

Could I get some clarification on how to abuse warlock's curse while being a fighter/blackguard? Thanks!

Since you can only apply your Curse damage once per round, so doing something like a close attack wouldn't let you benefit from it on two targets.
