Crafting will include Metal, Leather and Cloth headgear. There might be bits of animal bone/scale in there as well.
Openface Helmets:
Yes.
Raisable Visors:
Not initially, sorry.
Also I am fairly sure we will be able to include a variety of hats, tiaras, crowns and other accessories; but no promises. There is a lot of stuff already in the crafting sheets so I need to get the mechanically requested bits in first in order to complete the game. But rest assured, we do want more items and RP related gear so that you are able to further customize your character. We will add items over time since we fully intend to expand the game and add more to it in all stages of development and beyond.
Here are some concepts for helmets from the metal and leather categories. (This is an incomplete set and there are no guarantees all of them will be available and what others we cook up. This is all a work in progress.)
Cheers all
