• Living Radar.
You gain proficiency in Perception. If already proficient, you gain expertise instead.
• Tremor of Growth.
While standing on natural ground (soil, stone, wood, roots, plants), you can use a bonus action to focus your parasite’s senses. Until the start of your next turn, you gain blindsight out to 10 feet, but only for detecting creatures in contact with the same surface.
You can use this feature a number of times equal to your proficiency bonus per long rest.
