The best way to level up is to continue doing quests. Once you've done all the quests start doing the quest "Changing the World" in http://bravefrontierglobal.wikia.com/wiki/Atharva. The XP you get in this quest is almost as good as you get in Karma dungeons level 3.

TL DR:

1. Karma Dungeon Level 3 (Monday's)

2. Changing the World Antharva (After finishing all quests)
