Aspect of the Earth

The ground beneath you quakes in fury as rubble begins to encase your body, enveloping you in raw, magical earths. Your body looks completely encased in rock to those around you, though you can see very clearly. The magic earth surrounding you gives you the following benefits:

• You are immune to poison and non-magical bludgeoning, piercing and slashing damage, as well as becoming resistant to magical bludgeoning, piercing and slashing damage.
• Your Strength score is set to 20, unless if your Strength score is already 20 or higher.
• You gain proficiency in Constitution saving throws if you don't have it already.
• You gain a burrowing speed of 60 ft. as the earth shapes itself to around you to accommodate you. You can burrow through non-magical stone and earth without disturbing it. If the spell ends while you're burrowed, you're magically shunted to the nearest available space.
• Your unarmed strike, while in this form, deals 2d8 + your STR modifier as magical bludgeoning damage. You can make two unarmed strikes while in this form.
• When you make a melee attack while in this form, you can force the target to make a Strength saving throw against your spell save DC. On a failed save, the target is knocked prone.
• You can cast erupting earth at will.
