I love clever equipment ideas. I was reading a post about carrying torches and using them as improvised weapons, which made me think of this...
Iron Torch
This device is type of aspergillum designed to hold oil in its reservoir. A wad of cloth or batting can be stuffed into the top and lit. It gives off the light of a torch and burns as long as a flask of oil would burn.
If used as a weapon, the first attack splashes burning oil on the target if it hits.
Thoughts?
