Enervating shadow works during daytime if the warlock is inside darkness spell, but if a mist horror teleports to the warlock, a message pops up saying the spell dissipated due to a nearby light source. Recasting enervating shadow results in the same, the warlock must move an inch or so to "get rid of" the light source. This bug happens frequently in the mists where multiple greater mist horrors jump at me one by one.
