Galeb Duhr's Might

You have developed traits similar to those possessed by a Galeb Duhr, granting you the following benefits:

Ability Score Improvement. Increase your Strength or Constitution by 1 to a maximum of 20.

Boulder's Defense. You gain a base AC of 13 + your Dexterity modifier, while you aren't wearing armor.

Earth Sense. You gain tremorsense out to a range of 60 feet.

Earth Speak. You gain fluency in Terran.

Boulder Guise. You have advantage on Dexterity (Stealth) checks made to hide in rocky terrain.

Boulder Form. As an action, you can cause rock to form around you, fully encompassing you in a shell of stone, for 1 minute. While you have this shell of stone you gain the following benefits:

• Your AC becomes 14 + your Dexterity modifier.
• You gain resistance to nonmagical bludgeoning, piercing, and slashing damage.
• While you remain motionless, you are indistinguishable from a normal boulder.
• If you move at least 5 feet on your turn, you can opt to roll rather than walk. While you are rolling your speed increases by 10 feet. If you are rolling downhill, your speed is doubled.
• If you roll at least 20 feet straight toward a target and then hit it with an unarmed strike on the same turn, the target takes an extra 3d6 bludgeoning damage. If the target is a creature, it must succeed on a Strength saving throw (DC 8 + your proficiency bonus + your Strength modifier) or be knocked prone.

Once you use this feature, you can't use it again until you finish a short or long rest.
