[@Oblivion666]Sorry if my post is crap, but i hope it sets the scene well enough. 

Edit:Stalkers are stronger in that they wouldn't die from one hit like most flesh contsructs. It'd probably take a couple hits to kill them, though the mind venom could make it easier . . . or harder. Does the target need to have sentience in order for that stuff to tkae effect? If so, then it won't work on the constructs. Stats are that they're fast, make little noise while moving, and mainly ambush hunters. They hunt by sensing the heat signature of their targets as well.
