Well it was mostly to Rubah on the damage output and levels, since he asked for that part

That fight was a long time ago, I did it sometime before the jungle though. I think I was in my 20s or 30s. It was not "easy"(if by easy.. meaning I never had to heal much and it went down fast...)... but it was certainly not raising an ally every 10 seconds like Gilgamesh or some of the later fights at lower levels.

I think Protect had him hitting around 300-400... and stomp seemed to be slightly more than that to the whole party. But memory could be flaky.
