Alchymist

Not convinced by description of maimed at present. Fine for frontline fighters, probably good enough for archers who will not be able to hit a barn door. It's not clear how it will affect spell slinging classes though. Perhaps maimed should be implemented like level drained in D&D, particularly if level 0 characters exist. I've never liked the idea of recovering from death after one night's sleep, either. As a minimum, force characters to rest in a hospital/temple rather than lying on the ground in a campsite.

Not always quite so simple. I think that the roguelike called Valhalla (or Ragnarok) had some additional checksum calculation so it could identify copied and restored games. In the limit, locally saved games could be as difficult to modify as viruses if they really wanted to go that far.
