Okay I must be missing an obvious one here, hopefully someone can crack me on the head with the +3 Hammer of doh!!!
The rules state that the twilight cost of a card must be paid in order to play it. Given that there's 5 points on the twilight bar a cost of 4 will shift you from one side to the other. However, there are some twilight cards out there with a cost of 5 or even 6!!. I've had a look through all the cards and cannot find any modifiers for the characters with these high cost cards which would ever allow them to be able to afford it.
If anyone out there can shed light on this it would be much appreciated
