You can ritually cast Augury once a day. Restores on the next dawn. Only the Snake God Yig can answer from their knowledge.
You can also charge the yig statue by dedicating either 2 Hit Dice or 1 slain enemy to Yig.

By spending a dedicated charge,you can summon a giant constrictor snake, it is considered a natural ally to you. Should the giant constrictor snake kill a creature, the slain combatant is sending into the far realm to become a disciple of yig. Yig may choose to bestow a boon provided certain criteria defined by the DM. You can discuss what that boon maybe at a later time.
