When I use Wand of enervation, after I roll the amount that the check is decreased by, it removes the extra dice from cards I played.

Old bug From previous builds, but good to know that it still exist. Waiting some later patch.

You have to play the Wand of Enervation first, before you play anything else on the check, due to the bug.

Or after playing the Wand you need to cancel other previously played cards and played them again. It works fine.
