I've just been pushing options around in a 2250pt list that I'm working on for an up-coming tournie and the Crystal of Midnight caught my eye. At the same points cost as a dispel scroll (which is what it's competing with) I thought it might be interesting. My line of thought is that it will inhibit the actual volume of incoming magic over the whole game, making itself as handy as a dispel. I know I'd have to wait until the opponent was already on the back foot in any particular magic phase (it's only power level 4) but it could really spoil a low level's day or take a bit of the wind out of a TK sails. Thoughts and comments please- especially if you've used it in 2250pt tournaments!
