Your Constitution score increases by 2. In addition, one other ability score of your choice increases by 1.

You are an Elemental.

You are Medium.

Your base walking speed is 15 feet. When not moving uphill, you can use a bonus action to roll into a ball, increasing your speed by 15 feet, or 45 feet when rolling downhill. You can not take the Dash action during the same turn.

Your stone body gives you remarkable resilience, represented by the following benefits:

• You don’t age or need to eat, drink, or breathe.
• You are immune to disease, poison, and petrification.
• You don’t need to sleep, and magic can’t put you to sleep.

When you take a long rest, you must spend at least six hours in an inactive, motionless state, rather than sleeping. In this state, you appear inert, but it doesn’t render you unconscious, and you can see and hear as normal.

You have a base AC of 16 (your Dexterity modifier doesn’t affect this number). You can’t wear light, medium, or heavy armor, but if you are using a shield, you can apply the shield’s bonus as normal.

You can use your stone appendages to make unarmed strikes. When you hit with them, the strike deals 1d6 + your Strength modifier bludgeoning damage.

If you roll at least 20 feet straight toward a target and then hit it with a melee attack on the same turn, the target takes an extra 2d6 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.

While you remain rolled up and motionless, you are indistinguishable from a normal boulder.

As an action, magically animate a boulder you can see within 60 feet of you. A boulder shares your statistics and traits, except it has Intelligence 1 and Charisma 1, it can’t be charmed or frightened, it can't cast spells, and it lacks this action option. A boulder remains animated as long as you maintain concentration, up to 1 minute (as if concentrating on a spell). Once you use this trait, you can’t use it again until you finish a long rest.

You can see in dim light within 30 feet of you as if it were bright light and in darkness as if it were dim light. You discern colors in that darkness only as shades of gray.

You can detect and pinpoint the origin of vibrations within 10 feet of you, provided that you and the source of the vibrations are in contact with the same ground or substance. Tremorsense can't be used to detect flying or incorporeal creatures.

You can speak, read, and write Common, Terran, and one other language of your choice.
