What is giving you a 5' cone?
And searching around (I searched, honest) it looks like Undine can get one too. (ooze breath, yuck)
One square makes sense, but the magic chapter talks about picking a corner and counting squares, so I wanted to make sure it wasn't a semi-circle.
Any thoughts on reach? I guess if I pick a corner, it can't work on the square I'm in, so I can't spray someone who is sharing my square.
