So....
My players came up with this:
Fireproof suit
TL10 Cloth
TL12 Cloth
Boarding Vacc Suit
For total protection of 25 - doable?
The argument is, TL10 cloth is worn like clothing, thus the Fireproof suit and TL12 cloth can go under it, then the Vacc suit goes over the top of all that since a Vacc suit can be worn over clothing.
Hard to argue with it based on descriptions alone and little to no guidance in the mechanics. My concern is with situations like this, it gets to be a challenge to challenge characters that can get to such high protection levels. Most flora/fauna can't penetrate that, and my derelict ship with the yellow-musk zombies was not even a nuisance, though it was still fun.
I just thought I would bounce this off of folks and see what fell out.
