The opposing argument:
Ok, this gaming group happens to be the one i play in and since people here were wondering about the other side of the argument, ill provide it, along with corrections to a few fallacies I've noticed
to ekimus and sonoflilith: sorry to go against the group here guys, but i agree with the dm
First, as I remember it... it WAS a random encounter.
Second, the barb spotted the harpies and then turned to face them... he COULD have outran them if he had so chosen... the wings have a speed of 90', harpies have a speed of 80'... this was hubris
Third, our dm is no where near being stringy on magic items. I, as a player, have commonly voiced my opinion on this... perhaps it got through i dont know.
Fourth, the barb was seriously unbalanced, he has had, amoung others: rod of lordly might, sun blade, frost band, flame band, AC +12 armor. We seriously just let him into a room and watch the carnage fly.
Fifth, the Vampire incedent was grossly misunderstood. This vampire DID have it coming to him, there have been many, many, very powerful people hunting him, and i mean many.
The encounter went like this. Vampire casts spell on other mage (this mage had been sent by another mage SPECIFICALLY to watch over this vampire) spell fizzles due to anti-magic field, other mage DROPS anti-magic field, uses control undead, vampire fails save, mage orders vampire into stream of RUNNING WATER, not an ocean of still water.
Sixth, We have a hell of a lot more than the 5000gp ekimus said, its becoming insane
on SonofLilith's side
The harpies first instinct, in my opinion, would have been to eat him. This would very likely have woken him up out of the charm and allowed him to wreak the massive ammounts of havoc he always did
Seriously though, the barbarian became a LOT more interesting after he lost all of his stuff. He stopped looking like a mage, glowing with magic, and more like a barbarian with only a single ludicrously oversized sword.
I hope I've added some nice fuel to this debate
flame on!
