Also, there are many things that I wonder. We can only use shields, but can we dual wield shields?
Can we use more than strapped shields? What about center grip shields?
Here is how I think we can improve our offensive ability with designs alone:
Both two-handed and strapped versions. Pretty straightforward: just take the edge of the shield and either sharpen it or make it pointy, if not both.
Also pretty straightforward. Maybe more difficult to make, but this is a fantasy land, so who knows.
Big spike on the face, sharp edge designed to catch swords, integral blade and gauntlet, and IIRC, it also has integral spikes for the gauntlet to hold.
A little over the top? Maybe, and we don't really need the lantern, but otherwise it seems pretty damaging.
