How many heros are there? Is there a hero for everything at this point.
It was mentioned a few times that there are 10 heroes. (Well, up to 10 heroes, at least. It can take a few years for a new hero to replace one who died, and several of them have died recently.)
So far, we have seen: Healing, Magic, Sword, Cannon, Axe, Gun, Spear, and now Whip and Hammer. So there could still be one more.
