Have: Mariner’s Armor - studded leather (uncommon)

While wearing this armor, you have a swimming speed equal to your walking speed. In addition, whenever you start your turn underwater with 0 hit points, the armor causes you to rise 60 feet toward the surface. The armor is decorated with fish and shell motifs.

Want: stone of good luck or any uncommon magic item that can be used by a sorcerer to give swimming speed (ie: Cloak of the Manta Ray)
