The Sharkskin Shield is a powerful enchanted item crafted by a sea elf wizard named Aerin centuries ago. She created many of them, gifting them to the warrior caste that protected her underwater city, Nautilynth. They became a status symbol among the field officers and were passed down through the generations. However, after the disappearance of the entire city, the Sharkskin Shields were lost, only occasionally being discovered washed ashore on a beach or found by divers caught in a reef.
Sharkskin Shield
Armor (Shield), Uncommon (Requires Attunement)
This shield is covered in preserved sharkskin with an inner ring studded with shark teeth.
You can use an action to speak this shield’s command word, doff the shield, and throw it on the ground within 10 feet of you. If the shield is in an area of water that is at least 10 feet by 10 feet and 5 feet deep, it transforms into a hunter shark under your control and acts on its own initiative count. By using a bonus action to speak the command word again, you return the shield to its normal form in a space formerly occupied by the shark.
On your turn, you can mentally command the shark if it is within 60 feet of you and you aren’t incapacitated. You decide what action the shark takes and where it moves during its next turn, or you can issue it a general command, such as to attack your enemies or guard a location.
If the shark is reduced to 0 hit points, it dies and reverts to its shield form. The shield then shatters and is destroyed. If the shark reverts to shield form before losing all its hit points, it regains all of them.
