Burrow

You become magically attuned to the earth around you, enabling you to traverse soft ground such as dirt, sand, mud, or ice like a fish in water. Until the spell ends, you have tremorsense that extends out to 60 feet around you, you gain a burrowing speed of 60 feet, and you can hold your breath for 10 times the normal limit.

While burrowing using this spell, you can use an action on your turn to make a melee spell attack against a creature that is above the ground within 5 feet of you. On a hit, if the target does not have a burrowing speed, you pull the target partially into the ground, causing them to be grappled (escape DC equal to your spell save DC) and restrained while grappled, though it is not a magical effect, and they are grappled by the earth, not a creature or spell.

If this spell ends while you are still underground and you lack a burrowing speed, you become trapped underground until you are excavated or you manage some way out on your own. Without the aid of magic or excavation, you will suffocate to death.
