Wow. I did not realize its AC would be so good. I was fighting against it, so I did not even look it up. The wolf will not go on full defense until it would have hit at least once.
Round 425: Miss with touch. Wolf's bite goes through Nick.
Round 426: Hit with touch for 2. Wolf is at 131 HP and goes on defensive.
Round 427-9: Miss three times, once rolling a 20.
Round 430: Nick, realizing this wolf is tougher than he thought, merges with it. The wolf resists control (Will save 29) (This thing has a Will save modifier of +11?!)
Round 431: Last chance. The wolf resists, just barely. Aarghh! The battle is a draw.
Next in round 432 for Neutral is a huge ooze paraelemental (Manual of the Planes).
