Gleaming Prism of Elemental Harmony

Wondrous Item (Artifact), rare (requires attunement)

This multifaceted crystal orb, roughly the size of a grapefruit, shimmers with a spectrum of colors that seem to dance and pulse with an inner light. The orb feels warm to the touch and hums softly when held, resonating with the elemental powers that inhabit it.

When attuned to the orb, a character gains the ability to tap into elemental energies. Once per long rest, the user may invoke one of the following effects:

  1. Elemental Infusion: As a bonus action, the user may infuse a weapon they are holding with elemental energy. Choose one of the following damage types: fire, cold, lightning, or acid. The weapon deals an additional 1d6 damage of the chosen type until the end of the user’s next turn.

  2. Prismatic Ward: As a reaction when the user is hit by an attack, they can activate the orb to create a shimmering barrier of elemental energy. Roll a d4 to determine the barrier’s effect:

    • 1: Fire - The attacker takes 1d6 fire damage.
    • 2: Cold - The attacker's movement speed is halved until the start of their next turn.
    • 3: Lightning - The attacker must make a Dexterity saving throw (DC = 8 + user’s proficiency + user’s spellcasting ability modifier) or become stunned until the end of their next turn.
    • 4: Acid - The user gains temporary hit points equal to 1d6 + the user’s spellcasting ability modifier.
  3. Elemental Burst: Once per long rest, the user can unleash a wave of elemental energy in a 20-foot radius centered on themselves. Each creature in that area must make a Dexterity saving throw (DC = 8 + user’s proficiency + user’s spellcasting ability modifier). On a failed save, creatures take 4d8 damage of the chosen type (fire, cold, lightning, or acid), or half as much damage on a successful one.

This orb pulses softly with energy, resonating with the wearer's emotional state. If the user is subjected to damage from one of the four elemental damage types while attuned, the orb absorbs a portion of that energy, allowing the user to regain hit points equal to half the damage taken.

When the user is attuned to the orb, their eyes take on a prismatic sheen, reflecting the elemental powers they command. Additionally, they find themselves more attuned to the balance of nature, gaining advantage on saving throws against elemental effects and being able to speak and understand Primordial.

The orb is a potent artifact, but it requires balance and harmony from its wielder. A character who frequently engages with chaotic or destructive behavior may find the orb becoming unstable, potentially imposing disadvantages on its abilities for a time until the character demonstrates a commitment to harmony with the elements.
