In some groups, damage dealers are referred to as lumberjacks, since they're the ones who essentially cut down the "trees" of the massive hit point reserves of the enemies.<br/><br/>Similarly, you once got a "Wrath of God" xp bonus because in the computer game nethack, if you piss off your patron god enough, it fires a bolt of lightning at you.  If that fails, it fires a wide angle disintegration beam.  (most disintegration beams are defeated through magic reflection in nethack, but a wide angle beam can't be deflected so you need immunity to form changing.   Of course, if the disintegration beams fail, the god summons a ton of divine servitors to kill you)<br/><br/><br/>The extremely obscure references are mostly to amuse myself, and also be vague on where xp is coming from.  (bad habit, I know)
