Final fight was hard indeed but not impossible. Healing is a key factor (in my battle) so I loaded up Z with heal spells and let my monk, the dwarf, Jerro go nuts - iirc you've already said Garius true name so there isnt a need to do it again? Unless you're talking about the 3 shadow reavers?
That was the last time I remember using the True Name scroll and in that case it was just a matter of tanking them on the bridge so that they couldnt reach Ammon, lastly I believe she will fail the check everytime so let ammon do it - I think this is why its mandatory for those two 2 be with you - all u have to do is provide the tank.
Now the red dragon - forget it. I was easier for me to loot the hoarde while he killed 3 members, run out rez and repeat than to beat him. My 2nd run Im going to beat his ass but for my first run I unfortunately just went with the recommended stats/feats
Needless to say, when I saw the 2 black dragons later on I was even more sad about all the missed loot from these 3 beasts - can anyone list their loot?
