Wondrous item (requires attunement, very rare)
This whalebone amulet is carved in the form of a stylized fishhook twisted back on itself. You gain a +1 bonus to saving throws while wearing the hei matau. In addition, you gain advantage on Strength (Athletics) checks made to swim and Wisdom (Survival) checks made while at sea. You can also water walk for up to 7 rounds per day; these rounds need not be continuous.
As an action, you can drop the hei matau amulet into salt water, transforming it into a manaia, a magical giant seahorse with the head of a seabird (use the statistics for a riding horse, with Intelligence10 and replacing the hooves with:
- Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 [2d4 + 3] slashing damage).
The manaia shares a single language in common with you, and grants you water breathing while riding it. The manaia serves you faithfully for up to 7 hours per week, divided up in 1-hour increments; these hours need not be continuous. The manaia returns to amulet form if killed, the duration expires, or you take an action to command it to do so.
