Worked one of these down as a 26Rng/13Nin, was a decent fight. Lots of misses with capped Marksmanship (Marksmanship 81, no merits). The mob seemed to have between 850-900 HP.
This is a Blm/Whm, as it will Stoneskin often.
Would be a good mob for a Rng to solo between lvl 30-32. Good XP and at level 26, I was doing between 39-42 dmg per hit.
