I haven't noticed this being posted, but equipping Vierge with the ChronoRodG (Slow) makes the Hammer fight a lot easier, especially before self-destruction. I defeated him by accident without proper equipment because I got like, 8-9 turns after he turned red.

Umm, I know this is kinda late. Never had to look here when I had the game. I just remember that I turned mine in because I was playing on the psx when the game first came out and it locks on on that fight on a console too. not sure if it was every copy, though my copy did. Just thought it should be known about the game's coding glitch. And this was without attacking during my turn.
