Squid-Helmets (TL1+2) [10/12 pt]
Squid-Helmets are what you get when somebody figures out during the Bronze Age how to successfully train a tree octopus so that it can be usefully worn on somebody’s head, then the species gets selectively bred accordingly over the next few thousand years. By the time you hit a medieval-equivalent Tech Level you’ll have something that’s simultaneously useful, and not a little bizarre. But not creepy — or at least no creepier than a domestic goat or pig. Squid-Helmets live about thirty years, if properly fed; the species is almost extinct in the wild*.
