lol..now I call it a day .. being whacked by this guy 4 times tonight..
Bst lvl 70 with about 1300AC and 7,5k HP was tank. Bridgekeeper hits for upto 1405dmg and seems to have a ton of HP. Worst are the adds if the fight lasts too long. Got always heals interrupted and could not offtank them fast enough or mezz them at this long fight without missing a heal from the healers. Tash/Slow/Cripple seems to stick well but even then we were unlucky and last try after slow/cripple he only hit with about 300-400dmg but then we got a serious of 1k-1,4k hits in a row which neither the two healers could prevent nor the Enc could reslow him before tank died. Tried it also with a Ranger after the first two disasters but Beastie died again.. Ranger couldnt tank him after weaponshield wore off .. he ate him alive (Rng AC1300, 5,5kHP).. so you should have a really good tank with mitigation who does not get hit for up to 1405 in a series of punches ;-) but if tank is ok.. it should be surely easier.
Group was: Bst70, Dru65, Clr60, War52, Enc59/Rng66
I tanked him. Magelo: http://www.magelo.com/eq_view_profile.html?num=570996
I was buffed to 10150hp/1668AC, with clicky haste. shammy slowed on third attempt (70shm). after that it was cake.
In response to the post about him hitting for 1200+ and the risk-v-reward being whack, if they change the mask to unlimited clicky or worn effect (as currently listed by allakhazam), its quite worth it.
The mob only hits for 1200 occasionally (hit me for 1190 max actually), that is his max hit and any tank with half decent AC could tank it once slowed with ease. With 1510ac unbuffed I mitigated his hits mostly to the 500-600 range, and it never seemed to get much worse. No AE's or ramp/quads as far as i could tell, though he did enrage around 10%.
Of course he spawns in the same spot as the origional bridgekeeper. I wont bother explaining as im sure there are posts under the reg bridgekeeper regarding strats.
DROPS A FABLED MASK ULTRAVION 10 CHARGES? 95 HP 115 MANA/ENDURANCE 12 AC AND A FEW STATS NOT VERY IMPRESIVE FOR A MOB THAT IS LEV 70 AND HITS FOR 1200 WTH
