This is a "perimeter of effect" DoT spell. Wraps a shrinking band around units in an area which constricts them and deals damage. Flexible in application.
Approved. Just one (very minor) leak in function Trig_cast_Actions. If the spell id is not the correct one, you return before nulling the caster variable.
Learn this rule dude: "If my post has more than one smiley then my post is annoying to others"

Edit: wtf, I never saw this spell before, causes me pain since I wanted something like this after all the geometry stuff I learned when practicing last month...
