Thanks for the feedback. This is one of the monsters I am creating for my steampunk campaign.
The monster is based on the combination of the Scottish scarecrow called a "tattie bogle" and Scottish "bogle" myth.
Bogle - Wikipedia, the free encyclopedia
Tatter Boggles are pale colorless fey that live in abandoned potato fields. They have long black hair, bony faces, and recessed eyes. The fey collects lost belongings and the rubbish of nearby villiages to decorate its lair.
Tatter Boggle Lore
A character knows the following information with a successful Nature Check.
DC 15: Tatter Boggles will attack any intruder into their fields unless offered a gift of candy or milk.
DC 20: Tatter Boggles are well versed in local history and have an encyclopedic knowledge of everyone who was born or died near their territory
DC 25: Tatter Boggles are immune to cold attacks and vulnerable to radiant attacks. Tatter Boggles often raise giant beetles as companions and defenders.
DC 30: The potato bag cloth armor the Tatter Boggle wears is "dungeon delver" armor.
Tatter Boggle Tactics
A tatter boggle will attack first with its sink hole ability and then pelt the victim with rotten potatos. If immobilized or "bloodied" the tatter boggle with attempt to escape the encounter with a "Fey Step" teleport followed by a stealth check to hide. Giant Beetle allies are always sent in first and backed up by the ranged attacks of the tatter boggle.
Adventure Hooks
Outside of combat, the tatter boggle may be consulted on matters of local history given that it is "immortal" and has an interest in human affairs. It may also be consulted about more powerful fey in the area or the whereabouts of a lost item or buried treasure.
