The latter was much more successful in killing Captain Jack; but the remainder of the battle didn't turn out as planned, unfortunately.
With the first, there were always situations like Rain Strike getting in before Tetrakarn, making Tetrakarn a horrendous waste of MP every other turn, and the turns where not only does Jack go before Gucumatz, but he heals himself, making the Tetrakarn unnecessary in the first place.
Hurk.
Fornax is still incredibly easy, though. Mitra's, Horkos's, and Morax's upgraded formes were all nary a threat to me and my party's
all element coverage and shared alignment.In fact, the one trouble spot I ran into the entire time with Fornax was when I was Enemy Searching, slapping around the Kinnamon here and there and then suddenly running into a nearly level seventy Black Rider that has a peculiar fondness for the Megidola spell, which deals 500 damage to characters with 490 HP. It really is rather disheartening.
*sigh
Oh, and this got a laugh out of me:
[Got to the fifth level, and] I reached the end of the map and the boss but by that time I was fed up for having already invested 30 hours into bumping into walls and consulting online maps. Due to my constant wandering and being lost my team was so highly leveled that random encounters and bosses no longer provided a challenge or entertainment.
