Salvation Beam ruling
"Salvation Beam:
Make a Spellcast Roll (16). On a success, mark any number of Stress to target a line of allies within Far range. You can clear Hit Points on the targets equal to the number of Stress marked, divided among them however you’d like."
How do you rule that line? In my understanding you are not your own ally so you cannot exchange your own stress for HP slots. But does the line have to start at your position or can it be any line in Far range. For example my allies form a Frontline and a stand behind it can I target them all or do I have to be at the end of that "Frontline"?
The only other spell that I found with a line are the Wall spells which clearly states to choose two points and connect them.
The Art for the Salvation Beam card does not help at all by the way:)
Thanks in advance for the advice
