Grid Cone Confusion
Yes. A 15' cone is three squares long and three squares wide at that range. a 30' cone is 6 squares long and 6 squares wide at that range. Your frontal cone was 2 squares too wide in the first row, 3 squares too wide in the 2nd row, and 4 squares too wide in the third row. Your diagonal cone was a 25' cone but otherwise ok for that.
