At the end of August, I asked the people on my Discord server to each give me a random word so that I had some inspiration for new D&D poisons (I'm currently working on poisons for my upcoming sourcebook).
The words I was given were tremulous, disheartening, mercurial, and tender. From those I made these four new poisons:
The last two have more lengthy descriptions, so there's a PDF version for those that need it to be more legible.
Feel free to practice your Evil DM laugh before springing these on your players. Your neighbors won't mind.
