So I'm running Dungeon of the Mad Mage, and we were in the area with the throne that bites you with snakes, during combat with a flesh golem, 5 bandits, and a bandit captain, out Path of the storm herald barbarian was just tackling people and electrocuting  them because he was practicing "shock therapy", except for the Golem, of course. Our artificer was picking the bandit captain up and was picking her up and sitting her down in the throne so she would be poisoned, during that, our Sorcerer stuck his finger in her ear, nose, and eye, and gave her "surgery" aka just casting fire bolt. After we won, the "shock therapy" guy took a dead body and used some Sovereign Glue to stick a great axe head onto the body, and mace heads onto her arms, and so he dead body Greataxe was made. What i'm asking is, would the Body Axe have different stats then a normal axe?

The body would take some time to stiffen enough due to rigor-mortis as to be wielded properly, and even then a dead body weights several times a normal shaft.
On top of all, a dead body is not exactly the most durable material in the world, and in the long run it will break pretty easily due to the weakening of the tissues, bones included.
Stats would probably be horrible when compared to a normal Greataxe.

That being said, you people are sick, well done.
