Incorrect cone size and shape
So I was wondering, is there any way to make the cone work as per the 5th edition rules? The PHB states that a cone's width at a given point along its length is equal to that point's distance from the point of origin. This results in a 53 degree cone, unlike the 90 degree cone that the 5th edition ruleset uses.
We should have something like https://puu.sh/oKjvS/65cf027aa5.png that, instead of something like https://puu.sh/oKjxy/9ef95533ba.jpg that. The second only works if you use a variant rule for diagonal distance (where the second diagonal is 10' alternating.)
