- A wooden staff, decorated along its length with geometric inlay and carving. Both ends are clad in metal and contain a variety of fold-out gadgets (spear blade, grappling hook, etc.) — completely impractical to operate by hand in the middle of a fight, but that's not what they're meant for.
- A gleaming silver gun with an unusually large barrel and extra plumbing of unclear purpose. It's aiming for the “esoteric ray-gun” look, but still designed practically to accept magazines of ordinary (though custom) bullets.
