Tideheart Crystal
Wondrous Item
Uncommon
Tideward Barrier:
- When activated, the Tideheart Crystal projects a magical barrier around the ship.
- The barrier blocks or nullifies incoming spells, effects, or magical projectiles originating from outside the barrier.
- Spells cast from within the barrier function normally unless otherwise ruled by the GM.
Activation:
- Must be operated by a trained Arcanist.
- Activation requires concentration.
- If the operator loses focus, is incapacitated, or chooses to end the effect, the barrier immediately collapses.
Power Scaling:
The strength of the Tideward barrier depends on two factors:
- Tideheart Upgrade Tier
- Arcanist Power (rank of the highest spellslot)
Higher-tier crystals and powerful Arcanists can block even extremely potent spells.
The Tideheart Crystal is an ancient arcanotechnical device created millennia ago by the legendary mage-shipwright Azarion Vessenor. Mounted visibly on the deck of a ship, the crystal channels the vast tidal energies of the world Maris, a planet covered by roughly 90% ocean. When properly operated, it generates a protective field known as Tideward, a shimmering arcane barrier that blocks hostile magic from outside the ship.
Tideward was originally developed as a defensive measure against devastating magical warfare at sea. Throughout history, it has remained essential to naval fleets, explorers, and merchant vessels alike.
