Elgrim's Elemental Guide

You create a small summoning circle on the ground, place your ritual components inside, and perform the spell. Upon completion, you summon a Tiny elemental from a plane you specify while casting, or the DM chooses an appropriate elemental. For the next 8 hours, unless the elemental takes damage or is dismissed by casting the spell again, you gain advantage all Survival checks made to navigate through the terrain appropriate to the elemental.

For example, you can summon a tiny water elemental to aid with navigation on or under water, or summon an earth elemental to aid in navigation through natural caverns or mountains.
