Haystack

Haystack is an Environmental object that can be found in three different locations:

Act One

Emerald Grove

In the Emerald Grove a haystack can be found behind the Oxen at X: -99 Y: 619. Approaching it triggers a DC 9 Perception check, revealing its content on a success.

Its contents can also be revealed by using  Speak with Animals on the Bored Ox. He expresses his annoyance with the tieflings hiding "shiny bits" in the hay. Asking about the shiny bits reveals a pouch containing some gold and a gem.

Interacting with the haystack grants 15 XP.

Waukeen's Rest

At Waukeen's Rest a haystack can be found in the first barn at X: -99 Y: 619. Interacting with it triggers a DC 10 Perception check. If  Speak with Dead was used on Mirileth before interacting with the Haystack, the DC is reduced to 0, but can still be failed by rolling a 1 (Critical Failure).

If the perception check is passed, a Gilded Chest comes out of the haystack containing Mirileth's Dowry Ring, needed for completing  Rescue the Trapped Man.

Act Three

Rivington

Outside the Abandoned Windmill up the hill from Arfur's Mansion a haystack can be found at X: 56 Y: -36. Interacting with the haystack triggers a DC 25 Investigation check. Succeeding the check adds a single Arrow of Acid to the player character's inventory.
