This is a bit late coming to you, but after my first encounter with a Plague spitter
I realized i have been getting a lot more vitamins than any time before. So I took
1 it lasts about 12 minutes, Went after another spitter, and provoked it to spit twice
I only got mildly stung 1 honey and a sewing kit needed. Before that 2 honey sewing kit
and two red cross bandages. For the stumps it would be a crap shoot, but you can take one
vitamin, and run around for 12 mins busting them up, to build a basic supply of honey.
