You can squeeze through a space as narrow as 1 foot wide, provided you are wearing and carrying nothing.

You can see in dim light within 60 feet of yourself 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 draw your power and vitality from the magical Gem embedded into you, and said Gem derives it's power from the warm radiance of the sun (or any appropriate light source). So long as you are in the presence of an appropriate light source, you don't need to eat, drink, sleep, or breathe.

Outside of the presence of an appropriate light source, you cannot properly Long Rest. You must eat, drink, and sleep in order to reinvigorate yourself, but you only gain the benefits of a Short Rest. Additionally, you can hold your breath for 1 hour.

You have resistance to acid and poison damage, and you have advantage on saving throws against being poisoned.

As an action, you can reshape your body to give yourself a head, one or two arms, one or two legs, and hands and feet, or you can revert to a limbless blob. While you have a humanlike shape, you can wear clothing made for a Humanoid of your size.

As a bonus action, you can extend a limb or pseudopod that is up to 6 inches wide and 10 feet long or reabsorb it into your body. As part of the same bonus action, you can use this limb or pseudopod to manipulate an object, open/close a door or container, or pick up/set down a Tiny object. The extended limb or pseudopod contains no sensory organs and can’t attack, activate magic items, or lift more than 10 pounds.

By consuming enough calories in a short amount of time (three turns), you receive the effects of a Short Rest. If you are interrupted, the effects will not apply.

While inside your Gem, you cannot be healed through any means. Other characters can add your Gem to their inventory and carry you to safety. Your Gem is Tiny size.

If your Gem reaches 0 HP, it shatters and you immediately die. If the shards are gathered and dropped into lava (or anything that grants a Melting status), the pieces can be joined back together.

This class feature replaces all of the class's armor proficiencies, except for shield proficiency.

Your Gem houses an extradimensional space, which is no more than 9 cubic feet. Normal Encumbrance rules still apply to items stored inside your Gem.
