I have metroids on the brain (no they aren't attached like the friendly headcrabs) And in my creation of the said metroid npc stat block, i went looking for an ability that mimics there draining qualities. I didn't find one in the wiki, but i know one had been kicked around at some point. IF no one has it i will go ahead and script it and post it.
Also, i know that a stronger version of the Achilles Heel was kicked around in reference to vampires and sunlight as well, if not I can script it into the npc description.
The part I am having alot of fun with, is tracking down the amount of raw damage items do, to convert them to damage codes for a dice based system, using a fairly amusing scale.
5 Missles kills a frozen Metroid, how much damage does each missle do on average in a randomized enviornment, and using that to scale the various beam weapons that are persistant through out the games up until super metroid.
Thats whats going on in my head at 2:30 am on a sunday morning. I welcome all input as well, share the love.
