I have been working trick or Treat for several hours now, GM begging, and have received multiple covered chairs, heads on a pike and the other Halloween rares but no new skulls.... They are not the same chance as the other Halloween rares as a drop ? They are a harder drop ? How much harder ? I mean, I got like 5 covered chairs, 4 heads on a pike and a number of the other rares including guilloteens, but zero new skulls. Do they even exist ?
