Ring of the Four Seasons

Wondrous Item Legendary (this item requires attunement)

This item counts towards the Four Seasons set bonus. A ring with four flower buds entwined on its surface. Depending on the wearing Eladrin's season, a different flower opens. In summer, a rose with a ruby in the center opens. Autumn shows a citrine in the middle of a daisy. A forget-me-not opens and reveals a sapphire during winter. During spring, a carnation opens and reveals an emerald in the center.
For non-Eladrin wearers this item has no effect.

Summer: Gain access to the ability Raging Flames. One charge of Raging Flames can be consumed as an action to cause any flames within 30 feet of you, that you can see, to flare up to 15 feet in any direction of your choice, causing your level divided by 2 (rounded down) plus your spellcasting modifier fire damage to anything caught in the flames. Any creature caught in the flames must make a Dexterity saving throw or be blinded until the start of their next turn. You have a maximum of two charges of Raging Flames. Recover all spent uses during a long rest.

Autumn: Any time you take damage, you can choose to read your attacker's mind as a reaction. The next turn, any rolls you make against the target has advantage and any rolls that the target is forced to make directly from your actions are done with disadvantage. You may do this once per long rest.

Winter: Gain access to the ability Icebound Fortitude. Consume one charge of Icebound Fortitude as an action to coat yourself in a thick layer of ice. You can sustain this form for one minute. This effect gives you a number of temporary hit points equal to twice your level. While you have these hit points, Icebound Fortitude remains in effect. When these hit points are lost, Icebound Fortitude fades. While Icebound Fortitude is active, you are immune to cold damage, resistance to slashing, piercing, and bludgeoning damage and are vulnerable to fire damage. You may use Icebound Fortitude once per long rest.

Spring: You can cast Greater Invisibility. You may only target yourself with this spell. You can only do this a number of times equal to your level divided by 2 (rounded down). After a long rest, you regain all uses of this ability.
