You gain the following benefits while in this form: \n* You have resistance to cold damage, radiant damage, and bludgeoning, piercing, and slashing damage from nonmagical attacks. \n* You have advantage on saving throws against spells and other magical effects. \n* Your resonant crystal pulses with power, providing you with the benefits of all five harmonic frequencies. When you cast a spell of 1st level or higher, you can choose to activate only the Healing or Vitality harmonic frequencies or both. If you activate both, you can choose two different targets or the same target.\nThis feature lasts 1 minute, or until you dismiss it as a bonus action.",

It is a Tiny object and can serve as a spellcasting focus for your druid spells. As a bonus action, you can cause the crystal to shed bright light in a 10-foot radius and dim light for an additional 10 feet. You can end the light as a bonus action.\n  Whenever you finish a long rest, you can attune your crystal to one of the following harmonic frequencies. The crystal can have only one harmonic frequency at a time, and you gain the listed benefit while you are wearing or carrying the crystal. The crystal retains the chosen frequency until you finish a long rest. \n* **Clarity.** You have advantage on saving throws against being frightened or charmed. \n* **Cleansing.** You have advantage on saving throws against being poisoned, and you have resistance to poison damage. \n* **Focus.** You have advantage on Constitution saving throws that you make to maintain concentration on a spell when you take damage. \n* **Healing.** When you cast a spell of 1st level or higher that restores hit points to a creature, the creature regains additional hit points equal to your proficiency bonus. \n* **Vitality.** Whenever you cast a spell of 1st level or higher using the resonant crystal as your focus, one creature of your choice that you can see within 30 feet of you gains temporary hit points equal to twice your proficiency bonus. The temporary hit points last for 1 minute.\nTo create or replace a lost resonant crystal, you must perform a 1-hour ceremony. This ceremony can be performed during a short or long rest, and it destroys the previous crystal, if one existed. If a previous crystal had a harmonic frequency, the new crystal has that frequency, unless you create the new crystal during a long rest.",
