Ash held the toad skin above her head with what little pride remained. With the sudden rain pouring down on them, the disadvantage turned to advantage as the skin slowly but surely lost the layers of mud and blood. While the rectangle she cut wasn't huge (at least, compared to the froad), it was large enough for two people, three if they really tried. 

While visibility was cut, smells were also a victim of obfuscation. This meant that Ash didn't have to smell that eye. It was pleasant. The feeling of mud on her shoes and water permeating throughout her clothes wasn't a bad feeling. It was uncomfortable for sure, but it beat many things. For instance, getting stabbed by a goblin. The rainwater was also pretty nice. With her head leaning out from underneath the safety of the toad skin, she could drink the occasional collection of raindrops. It was water and it was nice.

Well, it was the calm before the storm. Or possibly, the storm before the even bigger storm of skeletons and zombies.
