How could I get 2 levels a day? What with gainig exp points, building up my shrine and meditating, it seems to take ages! Am I missing something?
Clear dens, mines, caves etc. Collect research items from those zones and Anomalies. Complete quests. Open all the chests that periodically appear in your towns. Kill all the monsters that periodically appear in your secondary towns. Go fight other people (Be careful with this one). Grind grind grind those dens some more.
So no, you're not missing anything. It takes a while!
