Alchemical Rat (Patreon)

Not every alchemist is as careful about discarding the results of their failed experiments as they should be. Sometimes these liquids get tossed down a sewer drain where they mix even further with the sludge flowing through the pipes. Swimming through these magical liquids can sometimes cause the denizens of the sewers to be infused with magical properties. Rats seem to be the most susceptible to the effects, increasing in size and gaining magical abilities and stronger resistances.

Every new adventurer has learned to fear rats... here's another way to remind them just how dangerous these beasties can be!
