Well thanks!

The Darkness replacement value statement actually got me to thinking how important the material csi quoted from the rulebook is. With Darkness/Deep Shadows range replacement value taking effect in the beginning of the game, it removed the conflict over Pulse Wave's range replacement in conjunction with Darkness/Deep Shadows. Once this rules passage was embraced firmly, it got rid of a "slightly icky" ruling that an 8 range Pulse Waver affected by Darkness/DS could Pulse Wave to a range of 4 (8 halved is 4 which is less than 6).

Thanks to that "embracing" it is now Darkness/DS range replaced at the beginning of the game, and then the Pulse Wave replacement takes effect during its action.

I've repped him for you. But hey, feel free to do it yourselves as well...
