Just a suggestion, I know we wanna stay clear of custom things but I'm just throwing this out there:
Whilst we have no use for "Jar of Swamp, Dirt, etc" could we get a use for it?
Proposal for Swamp jar is to Use it on the fire at Zul-Andra and you get in return a mutagen + 1/100 roll chance at the pet table? Maybe use this concept in other places too.
