Frank Mentzer & co. at Eldritch Ent have been drawing some flak for the "system-neutral" descriptions in their products. Apparently, to avoid being beholden to the Open Game License, they have decided to express key stats in terms of percentages so a 6 HD monster has 30% "Power" and so on.
(is there really a reason to list hit points in an adventure? Most times I just roll them up in the dicebox with my bucketload of d8's)
Defense: 4 (add to 11/subtract from 10 for AC; you can even break this down into physical, active and magical defense)
Attack: 3/3/6 (die maximums will do, you can figure out whether it's 2d6 or d12)
Speed: 3 (x30' for D&D movement)
SA: Paralyzation (give duration in minutes, maybe just let the DM work out the save or use synonyms for Fort/Ref/Will)
SD: undead blar blar
