Depending on how you came to be you are either a golem or an elemental.

You are  medium or small.

Your walking speed is 30 ft

You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of grey.

• If you start your turn with fewer hit points than half your hit point maximum, you must succeed a dc10 Wisdom saving throw or move directly towards the nearest creature and use the attack action against that creature. If you are concentrating on a spell or under an effect that prevents you from concentrating (such as the barbarian's rage feature), you automatically fail this saving throw. You gain resistance to psychic damage for the duration of fury
• If you have the extra attack feature you can choose whether to use it for this frenzied attack. If more than one creature is equal distance from you as your original target, roll randomly to determine your target. Once your attack is resolved you regain control of yourself.

Because of your nature you do not struggle with traversing rough and inhabitable regions. Therefore when traversing your region of origin or a similar region you will not be affected by difficult terrain.
