how do u kill the ravenger ? i tried but he sure does have alot fo hit points lol

He has over 500 hit points to be more exact, plus with his 75% or so damage resistance hes one sonofab*tch to take down.
I personaly didnt find him that hard to take down, however my group had 4 fighters plus Imoen (as a thief like she should be!) and Aerie, who with some spells could pass as a decent one. I summoned some elementals and some mordenkainens swords to engage the bone swords he kept summoning, while my 4 main fighters (Me/Inquisitor, Valygar dual wielding, Mazzy, and Anomen) unloaded high level fighter abilites and pounded the crap outta him with Imoen backstabbing for some extra kicks. He droped in about 5-6 rounds easy. :D :D :D

ya ur right at first it was hard to kill him but i just put whirlwind on all my guys and pounded his ass so much he couldnt cast a spell or even get an attack on.
