Earthshaper

Burrow

3rd-level Earthshaper feature

You've learned how to dwell under the earth. You gain a Burrow Speed equal to your Speed. You can use your Burrow Speed to move through sand, earth, mud, or ice.

When you reach level 7, you can burrow through solid stone and rock. The terrain shapes itself to your presence, assuming its original form after you've moved along.

Earth Strike

3rd-level Earthshaper feature

You've learned how to use the earth to attack your enemies from below. While you are at least 5 feet underground and within 30 feet of an unoccupied space that is above ground, you can use your Bonus Action to shoot upward through the earth, coming 5 feet above the ground upon doing so. All creatures within a 15-foot radius Emanation from you must make a Dexterity saving throw or take 2d10 Force damage, or half as much damage on a successful save.

The DC for the saving throw equals 8 plus your Constitution modifier plus your Proficiency Bonus.

This damage increases to 4d10 at level 7, to 6d10 at level 10, to 8d10 at level 15, and to 10d10 at level 18. You can use this feature a number of times equal to your Proficiency Bonus, regaining expended uses after a Long Rest.

Mobile Mole

7th-level Earthshaper feature

You've acclimated to subterranean environments. You gain Tremorsense out to a range of 60 feet.

Also, whenever you are using your Burrow Speed, you can Dash or Disengage as a Bonus Action.

Rocky Terrain

10th-level Earthshaper feature

You begin to tip the ground your enemies traverse. After using your Earth Strike feature, you can make the ground within the radius Difficult Terrain until the end of your next turn. You and creatures of your choice within 10 feet of you are not affected by this Difficult Terrain.

Enhanced Earth Strike

15th-level Earthshaper feature

Your Earth Strike's power enhances greatly. You can choose to expend a use of your Second Wind or another use of your Earth Strike (no action required) to enhance the effect of your Earth Strike: any creature that fails the saving throw is knocked Prone, and the Difficult Terrain caused by your Earth Strike instead lasts for 1 minute, requiring your Concentration for the duration.

Terra-ble Surge

18th-level Earthshaper feature

You've mastered the ways of harsh terrain. You are no longer negatively affected by Difficult Terrain, and you gain the following benefits while within Difficult Terrain.

Hazardous. You have Advantage on all ability checks, and on saving throws against effects that you can see.

Excavated. You cannot be forcibly moved, and you have Immunity to the Grappled and Restrained conditions.

Riveted. The range of your Tremorsense increases to 300 feet, and you can sense through solid surfaces and liquids that are connected with each other.
