Bandana of Creaturespeak That Also Changes Colors

For as long as you are wearing this bandana, you are able to comprehend and verbally communicate with any creatures that have intelligence scores no more than +3 above your own. The creature's sentience and knowledge are determined by its intelligence, and if its intelligence is a +4 or greater above your own, you must succeed on contest of persuasion vs the creature's wisdom, or the creature will not talk back. When a creature does speak, it can, at a minimum, give you information about nearby locations and their inhabitants, including whatever changes they have noticed within the past day. The bandana makes it possible to persuade a beast to do a minor favor for you, according to the DM's discretion. 

Additionally, the bandana's mottled color changes to reflect its immediate environment. For example, in a forest, its colors will swirl and mix into shades of green and brown, in a dungeon it will look like the stonework, in a pile of coins it will look metallic, etc.

Notes: A strip of linen dyed in shades of mottled green and brown. The spell-infused dye allows the strip's wearer to comprehend and communicate with animals, and it also changes color to match the surrounding environment.
