A great hit with champions of the undead and the not-quite-so-living. The hammers of Rot are an interesting weapon to wield and positively deadly to face. A hit from one of these weapons will transform the struck area into dead flesh or will strip it of its flesh depending on how injured the opponent is. The more damage an opponent takes the more he prematurely decomposes. These weapons are mainly found in the arsenals of undead champions, or are perhaps held by a necromancer who prefers to fight instead of wasting time and energy summoning the dead. It isn't that rarely that one can also be found in the possesion of a military commander or officer as well as with the undead.
As with every weapon of this sort however there is a downside, which in this case just happens to be that the more the wielder uses the weapon the more he gradually begins to look like a cadaver, and in time, perhaps over a period of years he becomes indistinguishable form a real cadaver.
Today very few of these weapons remain most having been found by paladins and other holy and righteous orders and destroyed. But they will come back to the surface every now and then, occasionally in the hands of the demented and oft insane. Go to Comment
The creation of intelligent magical weapons is not an exact science and there are occasional failures, as such think of causing a little more stress to your players by "rewarding" them with an insane magical weapon
Agrophobic, refuses to come out of the scabbard without a strength check to draw it.
Haemaphobic: afraid of blood, fight at a penalty against any blooded creatures but really good against undead, elementals etc
Schizophrenic, not just one mind in your sword, lets have half a dozen minds in there, all different and bound to cause confusion
