Very interesting weapon that can quite easily corner the market. I can picture seeing it in a d20 game too. How about adding a few rival companies who produce their own version of the weapon? Go to Comment
Giant mushrooms the size of trees. The stems and parts of the caps can be used in construction, and only the gills are soft enough to eat. An entire fungi-forest can grow in a matter of days, provided the correct conditions. Most fungus trees last about a month before collapsing, but not before a new generation sprouts to provide shade for the next spores.
