Stay On Target

The various flavours of D&D are games where you regularly fight monsters two or three times your size, if not even larger. Despite barely being able to tap the kneecaps of your opponent with a particularly long pike, you are able to inflict mortal wounds on a regular basis. It all comes out of the same pool of health, so if you stab someone in the same toe often enough they die. The death of a 1000 cuts is a viable tactic.
