FFIV: how to quickly level up?

Is there a way I can quickly level up my characters? I love this game but really don't like having to go around and find monsters just to level up. I heard about some cheat code that requires action replay device. I've never used such device and don't know if it might screw up my DS concole or the the game software itself.bqefhpasdgpihw

Don't use AR. It will screw up your game and system.

As for leveling up the best places I've found were outside the Dwarf palace western side. There is a pot that completely heals you on your way out that you can keep using. The Bahamut cave is also really good if you are that far. Dark Sages are easy to kill and show up in groups of 3.

I would recommend going to the furthest ahead dungeon place you can.

Make sure to have Teleport or one of those Emergency Exits, and go in as deep as you can, get the treasure, then Teleport out, heal, lather, rince, and repeat.

If you ever hit a point in the dungeon where the enemies are too tough, go back a little, train a bit, and then go back in.

Also, if you have the Level Lust Augment (can't remember where to get it, it's been awhile) give it to Cecil (if you only plan to do ONE run through the game and not a new game +. If you are doing a NG+, save the good Augments) because that would help him grow faster. To help him stay alive longer (so you can avoid death) give him the HP+50% Augment (Again, only if you aren't doing the NG+)

This is how I do it, if anyone else has a better way, I'd like to try it out...
