Easy Experience
Note: This only happens at the beginning of the game, and will not be available at any other point in time!* At the start of the game, once you've finished with any business in the town, proceed to the Land of Ardyl. Once you have arrived, proceed to kill any monsters the cross your path. Eventually you should receive a level up notice. Once you do, DON'T TOUCH THE EXPERIENCE POINTS! Instead, continue killing monsters. You should notice that you will receive another level up as quickly as you did the first level, as well as any other levels after that. This is because is takes the same experience to level up as it did the first time. You can continue leveling up in this manner until around level 14-17, when monsters stop respawning. *CAUTION: Once you do this glitch, DO NOT go into town, dungeons, or another area. This will cause you to keep the experience but stop the fast level up glitch, making you gain experience like normal! As soon as monster stop respawning, distribute ALL experience points before going anywhere!
