The four swords around Xuzl have around 156,000 HPs each, and put out around 312 Damage Per Second (DPS). That damage was taken by a well-equipped (Time, GoD, OOW) warrior, and the swords were fully slowed by a Shaman.
For comparison, Xuzl has around 550,000 HPs, and put out 250 DPS on that same tank.

We had no trouble slowing and debuffing the swords or Xuzl. He is apparantly tethered to his platform, so it's not possible to single pull him without aggroing the swords around him. We had no problem pacifying to single-pull the two swords in the front, then we attempted to pacify the back two and single pull Xuzl himself. We saw that he tethered back to his platform, so we just pacified one sword, pulled the other (Xuzl assisted, but tethered back). Pulled and killed the last sword, then rushed Xuzl on his platform for the kill.
Good journies, everyone!
