Ooze Core Pendant

This pendant is fashioned from a translucent, viscous material that resembles the core of a mindflare ooze, pulsing with an eerie, purple light. While wearing this pendant, you gain resistance to psychic damage. Additionally, as a bonus action, you can unleash a wave of psychic energy in a 15-foot radius centered on yourself. Creatures of your choice within that radius must succeed on a Wisdom saving throw (DC = 8 + your proficiency bonus + your Wisdom modifier) or be charmed until the end of your next turn. Once you use this feature, you can't use it again until you finish a short or long rest.
