I have a loving home for your spare and unwanted envenomed cloak scroll.
In addition to providing a good life for your scroll, I am willing to trade all sorts of shiny trinkets of your choice:
a bunch of red scales; and/or
larges (of any sort or any number); and/or
+3 greater hearts; and/or
plat; and/or
other goodies (I have lots of goodies sitting around--if you need it, there is a decent chance I have it).
Name your reasonable price and I will almost certainly meet it. Please feel free to PM.
