Summary of these new items: Unknown Item 171 - Level 5 Unknown Item 172 - Level 5 Unknown Item 174 - Level 83 - Probably a hat. Unknown Item 175 - Level 92 - Probably a hat. Unknown Item 184 - Level 46 - Probably a hat. - This one was a result from attempting to craft a hat... (?) Thanks to this thread.
