Despite carrying a dagger, this mob is most definitely a RDM. I sleep/nuked one in Halvung the other day, and I watched it cast Barwater, Fire III, Stone III, Thunder II, Regen, and Dispel. I'd send in a correction to Alla but my browser freaks out everytime I try.
Anyhow, classification errors aside, this was a pretty easy kill for a 71BLM. I wouldn't recommend trying with anything less than capped enfeebling magic though, since it resisted sleep quite frequently. Whenever that would happen ( maybe 2-3 times the whole fight ) I threw a Sleepga II, which put it to sleep. Using Stoneskin/Blink/Bind, I think I took maybe 100 damage the whole fight, and that was from a Fire III that Blink did not absorb. The entire process took about ten minutes.
Got about 150exp ( Sanction ) and some gil when it died, no items. Wasn't really hoping for anything- I just wanted to see if I could bring one down solo. ^^
