If the debuff has an icon, I haven't seen it yet. But if I kite a monster flame up here, and it touches me, I can't move or do anything other than listen to the music.
I see what's going on- you're not technically in the "stealth" region where monsters can't chase you, but the "on the hedge" flag turns on at the top of the stairs. I'll put together a fix for this and release it with the other ones.
