Hmm..
Ok, let's try this again.
A. Wolverine has no claws for this fight.
B. From second 1 of the fight, Wolverine is in pitch darkness and unable to see. Two magical scimitars stab him about a dozen times before he can figure out what's going on. He is then tackled by a 600 pound intelligent magical cat. Fighting Guen is a lot different than fighting an irrational and largely stupid bear. Guen would pwn the bear just as easily as Logan did.
C. Meanwhile, Cattie-Brie targets Matt, who is able to dodge her arrows, but she doesn't run out of arrows, so most of his energy is spent dodging. Wulfgar, Matt's equal in at least strength if not speed, keeps him busy for a while.
D. Bruenor sips some tea, and grumbles about the "durned elf" having all the fun.
E. Wolverine still can't see and is badly injured, but has dispatched Guen. Drizzt sends her back to the Astral Plane, then continues his barrage on the still-blinded Logan. Wulfgar and Cat continue to stalemate Matt. Bruenor joins Drizzt to pound the crap out of Logan.
F. Logan maybe gets a few hits in on the duo, but Bruenor handles it (he's crazily durable), then Wolverine falls over from blood loss or knock-out or something. They then gang up on Matt.
G. End battle.
