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:

1. Tideheart Upgrade Tier
2. 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.
