For my group the graffetti was a big clue to Drakthar's nature and after the run in with the were-rats in the bath house they decided to wait a day and pool cash to buy a silver weapon for the main tank (there were also one or two floating around in Life's Bazaar). With 2 clerics, a paladin and sister Jenya at the temple they had a decent chance to know something about vampires (via Knowledge: religion).
He ambushed them three times and retreated as soon as they started casting. Twice he nearly killed the Aisimar Paladin (once tossing him off of that rope bridge) so they returned to the surface. On their third encounter with him, in the cavern below is coffin, he dominated the Dwarf spiked-chain fighter who nearly wiped out the group. 3 players dog-piled the dwarf while the Duskblade got real lucky with a few "Kilgore's Fire bolts" and took down Drakthar.
Drak's got a huge AC vs mundane attacks but very few HP so a steady volley of magic missiles or ranged touch attacks really nuters him.
