Above: dressing room for monsters; ideal case (which per se means “seldom”).
The outfits are laid out in a big, well- lit room in the order the parts are dressed (overalls on top, masks last, lying separately where no one is likely to tread onto them). The NPCs have enough space, can actually see what they do and aid one another.
They can also check each other´s outfits before going out to war.
By the way: can the masks get damaged?
Sure they can. So what? The safety of the wearer comes first. Any damage occuring inplay (for example tears or parts getting torn off) can be repaired instantly.
The only irreparable damages is “compression damage”:
If somebody puts something on the mask that deforms it and it stays that way for a while the distortions won´t go away again and the mask is permanently deformed.
Also the changing area of the fundus has to be permanently controlled: exhausted NPCs first take of their masks and then get rid of the rest of their gear- an ill- fated sequence.
Therefore it makes sense for a member of the orga to be present and after the debriefing at once restore order when the NPCs have left to take a few minutes of rest before their next combat mission.
