At first glance that nightmare doesn't stand a chance.
I mean look : Never going to do enough damage to that failed summoner when it keeps getting healed every round. Taking damage from thorns, magic and the vulture...dead meat, right?
Wrong? Extra speed from the kitty and rage make it virtually untouchable. Even to the magic attacks due to phase.
Verdict: Speed kills. Don't underestimate a very fast tank's ability to stay alive.
