Cone Ranges and Cone Areas
the only thing the target determines for cones is where the center of the cone is, the actual cone should extend to the powers max range and max radius regardless if the enemy is right up in front of you or further back
+range enhances actually affect cones the most because extending the range also extends the area covered by the cone

So a cone always starts at the caster no matter where the "target" picked is? And i would love it if we could just fire these without a target. Cant tell you how many times my "centered target" in a group has went rabbit on me and my cone hits that one fool and a barren field. Thats truly one of the biggest downsides to these targeted AoEs.
correct, and i like aiming off a target, much easier to place it where you want then, the only cone that i know of that does not require a target is vorpal judgement and there are several problems i could see from not needing a target, mostly for flying characters

I have been playing a lot of Blasters recently, switching from my Brutaholic ways. So now i have questions about cones.
Most cones will have a range of 40 and a radius of 40, or sometimes a range of 80 and a radius of 80.
So, if I target somebody 40ft away from me is that where the cone starts, or ends? Seems like thats where it ends from play experience. But the wording is, as usual, quite inexact.
