Just a quick refresh

Hey guys I'm replaying IX for about the fourth time right now however its over a year since I last played it and I wanted to ask a question:

On disc 3 with the blue narcissis where is the best training area between levels 25 - 50?

at the moment I'm fighting hydra worms for 2002 exp with level up ability on all characters however I seem to remember being able to get more somewhere it's just I cant remember where :confused:

Fight Grand Dragons on the land above Gizamaluke's Grotto. Use Quina's Level 5 Death spell for an easy win every time.

Grand Dragons can also be found on Palmnell Island, which is the location of Chocobo's Lagoon. LV.5 Death can be learned from Whale Zombies, which inhabit the beaches of the same island.
