Where should I train?

Currently chars are levels 53-63, Grand Dragons seem kinda slow, where should I go?

One of the easiest ways for me was having Quina and Freya on my team. Basically what I did was just have Quina cast Lvl. 5 Death on some Grand Dragons. The reason I had Freya on the team was so her Dragon Crest attack would become more powerful (For a good reason) with every Grand Dragon I defeated.

Later on I moved on to Vile Island to battle some Yan's. If you killed enough Grand Dragons then Freya's DC attack should do 9999 damage to them which should make things easier.

Alternatively you could just go to Memoria and kill some Behemoths.

i normally got luck and started killing the grand dragons at like level 15, with my reflect and auto-life rings, so yeah, i got tired of fighting them as well, but in memoria the chimera seem to give the most exp.

Lol, grand dragons, hands down, slower but less deadly than Yans, I swear to god I killed Ozma, and landed on vile island for a sec, got into a fight and got destroyed by 3 yans, comet, and 3 snorts. I almost cried.

wow. that sucks. (note to self: do not land on vile island when you finally beat that ball.)
