It's a pain to level up, but totally worth it if you're trying to level up your Blacksmith or Armorer. Just keep using Survival Manual II and continue spamming leves. Make sure to mine every node you see outside of your quests as well. DoL seems like the slowest classes to level....so painfully slow. If you feel that it is too slow to level, just log out for a week to build rested exp and use a manual so you can get a 100% exp boost and grind a few levels that way. Rested exp can give you up to 200k exp and manuals can give about 9k.
