FormerlyHemlock
Hero
That's what the paralysis cone is for, but the Medusa also has no control over her power, both mythologically and per the rules, ANY CREATURE that sees the Medusa's eyes starts to(in 5th, in others and myths its just intsa-death) turn to stone, even the Medusa. That power, aside from being crazy powerful, would be absolutely terrible in an adventure. Want to talk to a merchant? Stone! Want to meet your party members? Stone! Pet the kitty? Stone!
Isn't that exactly why someone would want to play a Medusa? So they can have fun dealing with all those disadvantages?
