I don't want to weigh in on the current argument of whether or not drop chances should be affected by Monster Power level just yet. Obviously, we think it's a good idea and worth trying out, but if you feel differently, then I'd definitely like for you to continue discussing your thoughts on that topic. If you don't like it, tell us why. (Or, if you DO like it, be sure to weigh in too.)
I killed the act 3 keywarden on MP 10 once and the key didn't drop. (didn't have any NV stack though)
You'll need five stacks of NV in order for the keys and the demonic organ pieces to drop.
We felt this was a reasonable requirement, otherwise players could simply farm the keys in a lower MP, then set their game to MP10 and farm bosses for guaranteed drops. With the five stack, players will at least need to be able to kill monsters in that MP level in order to benefit from the increased organ drop chance.
