One problem is that the cold showers slowly kill you, which I just tested. In about half a minute, I had taken 25 fire damage. It cools your body down to 80 degrees (down from 300), too.
Seeing this, I decided to do some science. I made a shower cold, dealt 50 brute damage to myself, stepped in, and swallowed a 30u cryoxadone pill. Not only did I heal all the brute damage in a reasonably fast time, after I swallowed the pill I even healed the fire damage the horrendously cold water was dealing to me. I jumped between 1.5 and 3 fire damage the whole time. Not only does a shower work as ghetto cryogenics, it might even work better than cryogenics itself. It flash-cools whoever steps under, almost quartering their temperature in a split second.
Since there was no reason to stop with this already amazingly useful discovery, I took it a step further. I took 30u cryoxadone (pill) and walked out an airlock with no internals or space suit. There were a few things:
- Oxygen damage totally stalled. Normally, it takes reaching 0% health to black out, but taking enough oxygen damage (40 or so, it seems) makes you black out early. Useful.
- Brute damage slowly moved between 5 and 7 damage as I gained and healed it. Nothing interesting.
- Every five seconds or so I would take a few points of fire damage.
90u wasn't much different, except I took even less fire damage. Alas, it seems you cannot survive space indefinitely by chugging tons of cryoxadone when you go out. Still, it'll keep you going a lot longer than you should be able to.
