You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.

You can speak, read, and write Aranea.

Aranea are only capable of emitting chirps and clicks, making it nearly impossible to reproduce the complex sounds of speech. When you learn languages other than Aranea, you understand them when spoken, but cannot speak them yourself. Reading and writing is unaffected by this limitation.

Your Intelligence score increases by 2. Your Charisma score increases by 1.

By emitting ultrasonic clicks, you can “see” out to 60 feet. With this ability, you treat all locations with 30 feet as if they were in bright light and all locations out to 60 feet as if they were in dim light. This ability works regardless of the actual lighting level, magical or otherwise. This ability is blocked by magical silence.

Your legs are highly sensitive to the tiny vibrations in the environment, making you aware of the location of any moving or living thing within 5 feet that is in contact with the ground or objects you are in contact with (such as walls, floors, or ropes). You have advantage on Wisdom (Perception) rolls when attempting to locate a creature that is attempting to hide from you within your tremorsense range when that creature is not flying.

Persistent fog in your home lands reduced the benefit of normal color vision. As a result, your species has poor eyesight. All light sources are treated as being one level dimmer and you can see normally only out to 30 feet.
