After selecting a base armor type (padded, leather, scale, plate, etc), one can then set specific armor attachments from a wide array of pieces, stretching from a small padded kneepad to a massive full-plate pauldron.
Finally, to round out their appearances and to provide that ever-popular protection from the elements, the McProtagonists need some suitable armor. Tints were set after this, and in just a few moments one has a sword fit for hacking all kinds of various and sundry critters, and looking crazy impressive whilst doing so. Gretchen's greatsword started out all using the same model set, then the blade and pommel models were swapped to create a new look for the weapon. Certainly there are multiple models to choose from: but multi-part weapons such as swords and axes can actually have multiple models in one weapon, allowing the user to put together different heads/hafts/grips for their hackin' instrument of choice.
For valiant Gretchen the fighter, her greatsword works a little differently.
