where to train at lvl 68

[GM-Ayu]

If you got some key of the underground, bathory is fabulous place to train. Witched Starsand beats hillwind or sharp leaf in zeny worth (by selling to players and I'm very sure they will ALWAYS sell out), and their card is one of the best pvm card. Not overly difficult to dodge, low attack power, and you can mob them too if you are built for that. Auto counter against Joker and fly wing from the swords/jokers.

My own knight trained down there all the way until lv 97.
