[@Vertigo] Tanraeth recalls the following regarding the scale:

Tanraeth knows the object is as a 'bubbling scale' and this dark, iridescent scale is about the size of a small coin. He recalls that when one swallows the scale, one immediately begins to grow a patch of scales that cover the majority of one's body. For one hour he remembers, the imbiber will be able to hold their breaths for an extended period of time. After this time, the scales wither and fall off one's body.
