“ On a location with numerous webs, and at least one big spider, there is a something inside a cocoon. It is humanoid in shape, still moving. If the heroes free it (not before they kill or drive away the spiders), they meet a ... zombie!
The poor zombie wandered the dungeon alone, and tried to kill a big living creature (= a spider). The spider used the usual treatment, even if this victim did not look tasty. The zombie can be easily killed as any other zombie. It got but several doses of spider-poison, so can be something worth if it is extracted. You can mention to a druid or ranger the fact the spider had no poison anymore.”
“ The Langdon Ballistics company has a short and muddled past of producing shoddy and cheap weapons. Stocks are made of orange plastic with black paint coverings, and metal components of the weapons they make are typically low cost alloys. Their most famous weapon is the L-12 Scatter Rifle, a fairly high power large bore shotgun. It is easily recognized by its orange stock and pronounced ammo clip.”
