Destination: Your destination must be a space you can occupy without squeezing.
Instantaneous and Unblockable: When you teleport, you disappear from the space you occupy and immediately appear in a new space you choose. Creatures, objects, and terrain between you and your destination don’t hinder your movement in any way.
Immobilized: Being immobilized doesn’t prevent you from teleporting. If you were immobilized because of a physical effect, such as a creature grabbing you, you can teleport away and are no longer immobilized or restrained, if applicable. If you were immobilized because of an effect on your mind or body, teleporting does not end that effect; you’re still immobilized when you reach your destination.
