I’ve been playing this game on and off since it came out for Nintendo DS a couple years ago. Yesterday I managed to reach the Tower of Owen which requires that you cast Toad on your party to get into the dungeon. After realizing I didn’t have enough MP to actually cast the spell, I made my way to the nearest inn to restore HP/MP to my party members. I then went back to the tower and cast Toad on myself countless times, which did nothing. After searching on Google for 15-20 minutes, I came across an old forum post (which I can no longer find the link too). In any event the post described the same issue I was experiencing. You could cast Toad, a green puff would surround your characters, but nothing else happened and you continually saw the little scene that said you needed to turn into toads to get further into the dungeon.

The solution for me was that my party still had Mini cast on them, so the new spell wouldn’t work. After casting Mini on the party again (so they were regular size) I was able to cast Toad without any issues. Another solution was to make sure the “Always on normal status” cheat wasn’t activated if you were using an Action Replay device.

I do hope this helps someone, because I about stuck the game back on the shelf.
