Wondrous Item (Shield), Rare (requires attunement by a druid or cleric of Thal’vanna)

Description

Once the hull of the cursed pirate ship Blackstar Siren, this relic was salvaged by Myrryn Larthessa from the undead captain who once commanded it. Returned to the city of Azurlith as an offering to the sea goddess Thal'vanna , the fragment was sanctified before the Coral Throne — imbued with a single drop of Living Deepwater from the divine amulet Aquavanthe.

Now forged into a shield of holy brinewood and living coral, Tidebreaker serves as both armor and divine conduit, humming with quiet conviction when near undead or unblessed waters. It urges its wielder to reclaim purity and sanctify the Deep Queen's domain.

Waters of Reclamation

Tidebreaker bears a divine burden — to reclaim and sanctify the Deep Queen’s forgotten waters.

Rite of Purification (1/Use)

As an action, you may perform the sacred Rite of Purification:

• Trigger: You encounter a body of water untouched by Thal’vanna’s Deep Current (blighted, corrupted, undead, or aberrant-infested water).
• Effect:
• You plunge Tidebreaker into the water.
• The Living Deepwater within is released.
• The water becomes consecrated, cleansed, and aligned with Thal’vanna’s will.
• Any undead influence is repelled or weakened.

Aftermath:
The shield becomes a mundane hull plate, losing all magical properties. To reclaim Thal’vanna’s blessing, the bearer must:

• Return to Azurlith and present the plate at the Coral Throne, or
• Complete a divine quest assigned by a herald of Thal’vanna.
  Each Tidebreaker is unique, and each rebirth comes only through sacrifice.
