The entire gauntlet is amazingly easy, I did lots of (about 30) solo runs and about 40 runs whit a pally. You can just tank any of the bosses with your ww and vet it. There's no problem anywhere except sometimes when they mortal your pet a few times in a row, it might die, it might not.
The DF is easier then the abysymal (spelled wrong?) if you ask me, like said a few times, just lure it to the moongate and let it rip. You stay out of range of the whirlwind attacks and you can use your mare (with greater heals) to take out the (minor) spawn while you let your ww continue to bash the DF. The only tricky part is rotting corpses since they're hard to peace and a mare can't solo em without a peace..
Btw. I don't agree with the ppl saying that pallies or mages are the best in the gaunt without a tamer for support, tamers rule this land..
