I had insane levels from trying to get the summons. Thank god they carry over so I don't have to do it again, instead I'll be grinding for the Onion gear in my second playthrough. Despite having insanely high levels, I still found battles to be challenging in the game. Golbez was able to kick my parties ass several times despite Cecil and Yang being in the 70+ range. Equipment definetly plays a large role in this title. Despite half my party being maxed level when I got to the final dungeon, I still found the Dark Sages and Red Dragons to be more than I can handle through plain brute force. You really need strategy at the end of the game and that's why I love FFIV DS.
