Thumbs up for the change. Telepathic control over hellhounds or Underworld creatures is perfectly fine, as she's a "princess" of the Underworld. ;) Enhanced agility and endurance are also ok, but make sure she isn't near-invincible and still can be killed with swords or arrow shots like any other demigods, just that she won't die immediately. (I mean she's still a human not a freaking robot, yeah?)

I'll repost my character's sheet later, so that I can update it freely when the IC progresses. I don't have the power to edit your posts, haha.
