Breathing Potion

Description
"She waded out until the low waves were lapping about her waist; then she struck out strongly, swimming with a vigor that promised unusual enurance."

- The Devil in Iron

The Dregs have always been a dangerous place. When the Giant-kings would send slaves to clean out the sewers, they would often lose valuable servants to the creatures which dwelt in the sewers, not to mention those that drowned when a chamber suddenly flooded.

For the latter, at least, they could craft a solution. Using a combination of the strange glowing plants and heat, they created a potion that would allow those caught in water to be able to buy a few more minutes of precious breathing time.

Slaves still disappeared from time to time, but the scrutiny of the Giant-kings seemed to cause a great reduction in these incidents.
