A pearly white conch with a bright pink inside, it is at the pinnacle of perfection where conchs are concerned. It is always in perfect condition, yet is quite fragile. 

Abilities:

Confinement of the Treacherous: The Conch can be used once in its life to confine a creature of evil alignment. The creature must make a DC 25 Wis saving throw or be confined in the conch. On a successful save nothing happens and this feature of the conch can't be used again on that creature. While inside the Conch the creature does not age nor does it require food or water. The creature can be communed with by the attuned wielder of the conch, but the imprisoned creature cannot cast spells.  The confinement cannot be broken unless the conch is destroyed. 

Mark Of The Leader: If you are attuned to the Conch, any group without an identified leader instantly respects you as their leader unless you do them harm or have drastically different goals. A group with a leader must make a collective DC 16 Saving Throw, on a fail you become the new respected leader of the group. If the result ties the DC, a schism creates and half of the members join a new group lead by you, with the remainder staying with the original leader or dispersing. 

Goals: The conch seeks to protect the village and continue to confine the evil creature it harbors.

Destroying the Conch:   The Conch is quite fragile and is easily destroyed in the hands of someone that intentionally means it harm. This individual must be sentient and with an intelligence of 8 or greater. To destroy the conch one must simply state their wish and crush it in their hands. When  destroyed, it releases its magic in a dazzling display of  harmless energy and reforms itself in 1d100 years with its magic intact. When the conch is destroyed, any creature inside the conch is released.
