So I was looking at some of the cone diagrams and I looked at what it says in the dragon breath weapon about the cone shaped breath ones and something just doesn't jive.
A cone is as high and wide as its length.
This makes me think that 30 ft cone should be 30 feet at its widest, yet in the 30 foot cone diagram, it hits a maximum width of 40 feet (8 squares).
Are dragon breath weapons different than other cones?
