This black, silk formal hat complements a monocle and white-tipped cane. 
The attuned becomes aware of the existence of the matching cane and monocle and wants to unite the set. If another part of the trio comes within 5 miles, both owners can sense the general direction of the items and wants to pursue gaining the item. They can be persuaded to attend other activities for awhile. If 2 items are attuned and the last comes into range, the character will put seeking out the third as a top priority.

When attuned and wearing the hat, the character gains the Skilled feat. 

If Abram’s Hat and Abram’s cane are attuned, the owner gains ability to cast disguise self 2/day and alter self 1/day. 
(Edit item at that time.)

If all 3 items are attuned, the owner gains an extra attunement slot. 

Notes: Feat: Skilled, Anyone
