[h2]Sapphire Rode - Armory Class[/h2]
Sapphire took a look at the mask being offered her. It was a fairly basic design, a simple mask that covered the mouth and nose connecting to an oxygen tank to allow easy breathing. It wasn't the way that Sapphire would have designed a breathing apparatus. If she was going to craft one she would make something that filtered oxygen from the surrounding environment which would illuminate a limit on time spent there. However that type of device required knowing where you would be before hand and building it to make the specs of the environment you were trying to breath in. Gren's design was a more multipurpose model.

Proper hermetic seals were difficult to perfect. You needed an airtight solution that could instantly bond and release from any substance, for this type of device human skin. Those types of materials were generally expensive. There were of course some cheap alternatives but those resulted in a lower quality seal which could end up becoming compromised which depending on the environment you were in could get you killed.

"You're best bet for a proper seal would be a synthetic biopolymer. However those can be expensive. It might be possible to distill something off of another device from the scrap room but I'd have to take a look around. Of course there are some cheaper options too but those result in less... secure seals. Did you have an environment planned for this device? If I knew what it was planned for I might be able to specialize it somewhat for that location."

As she said this to Gren Sapphire listened to Chatsworth dole out today's assignment. She cursed under her breath. Sapphire had been hoping to use this class to work on her climbing, acrobatic apparatus' she'd started in math. Of course she could create a cheap pair of nightvision goggles in a half hour but she would rather have a decent mark in this class if she could. She'd think of something before next class. Something unique, she didn't want her inventions to be like every other assignment.
