A ring that gives Carl functional gills while making him slimy and slightly less charismatic.
When Fort Freedom's submerged battle becomes a trap, Carl equips the Water-Breathing Ring so he can follow Signet's force underwater. Gills immediately form along his neck.
The item also makes him look and feel slimy and lowers his Charisma by one point, prompting Donut to demand that he remove it. Carl keeps it on because he intends to dive into the rescue.
A magical finger ring whose activation produces visible neck gills and a slick coating over the wearer.
The ring makes Carl's planned underwater intervention possible at a minor social and cosmetic cost.
