Sun Sickness. While in sunlight, you have disadvantage on ability checks and attack rolls.

Languages. You can read, write, and understand common and undercommon, but you cannot speak.

Rapport Spores. All creatures within 30 feet of you with an Intelligence of 2 or higher that aren't undead, constructs, or elementals can communicate telepathically with you and with each other. You can suppress this ability at will.

Hallucination Spores. You can use your action to eject hallucination spores at one creature you can see within 5 feet of you. The target must succeed on a Constitution saving throw (DC 8 + your proficiency bonus + your Constitution modifier) or be poisoned for 1 minute. The poisoned target is incapacitated while it hallucinates. The target can repeat the saving through at the end of each of its turns, ending the effect on itself on a success.
