The effectiveness of Death Gaze really depends on the number of Gorgons, just like the number of creatures they kill!
For example, take 1 Azure Dragon. How many Gorgons are needed for Death Gaze to work? There was some formula somewhere... I forgot.
No, of course, that's obvious. I'm just interested in the formula itself, and I think the information isn't quite accurate. And for 1 Azure Dragon, you can definitely find a number so that the ability works for 1 Gorgon ;) (though you'll die faster :D)
