A creature in the zone takes any action other than a move at the begining of their turn, or ends their turn in the zone, takes x damage.
YAY. We all win.
Wording needs tightening. By "move" do you mean move action? Does a charge away work?
Also, it's not a zone (yes, minor nit but still...)
Any creature that ends any action, or ends their turn, adjacent to the sphere takes d4+Int damage?
I'd actually like to disallow shifts away too. Too easy to get away. Make them pick between provoking or burning perhaps?
