This is such a minor point but the "Change Blindness" thread is now buried and I don't know where else to express it.
The use of the abbreviation "DV" in the spell descriptions is not great. I just spent 15 minutes trying to figure out why spells listed a damage value before I realized in this instance DV is drain value. I feel like the word "Drain" would have been better in that section on those little tables.
As I said, very minor point. The rules do explain themselves, its just I feel acronym "collisions" should be avoided wherever possible.
