Oh yeah, Carry Armor..he is a bit of a problem even in the normal game, but as long as you use the enemy skill Magic Hammer, he really isn't that harmful.

If the boss battles up to this point has been any indication, then the bosses in this challenge will take a long time to beat, although aren't TOO hard up to this point. I just beat Dyne who is easily a once shot kill with a Right Arm. Jenova-BIRTH was a little monotonous and served to be a bit of a bore after a little while, but alas, there weren't many problems fighting her. Currently my party is as follows:

Cloud, Level 8
Tifa, Level 7
Aeris, Level 11

I'm dumping all the experience on Aeris because she is just going to die and nobody will know her level anyway. I am currently heading over to Cosmo Canyon, and that should be simple as well, as Gi Nattak goes down in a single shot with an elixir. I'm not entirely sure if the Stingers are susceptible to mini or toad or anything like that, because if they are, it will be very simple to beat them and get that over with.
