Musings about PCs and Prisoners

[Talakeal]

Pet Peeve, btw: Fumbles that involve anything like dropping weapons, hitting the wrong target, etc are not the inverse of critical hits. You know what critical hits do? One extra attack's worth of damage (or sometimes a bit less).

How is doing a single attack's worth of damage to an ally not the inverse of doing a single attack's worth of damage to an enemy?
