If you could create a unit...

[mivayan]

fair enough . But it has wings and snake hair as the more traditional Greek representation of the Gorgon... boooo hehe. The developers also implement petrification as a fear effect and not the ability to literally turn to stone [to my knowledge at least]. Lastly there is no unique ability for shielded units to avoid that petrification like in the tale of Perseus & Medusa.

Anything trying to attack the Medusa in close combat gets petrified (instant death), unless it succeeds a magic resistance check. It is a very cute ability and would make the medusa great if it was not wimpy enough to sometimes die from a few lucky militia. The unique shield the Aegis does the same thing.
