A great place to level-up in this game is at the Nebulous Dead Lands. Head towards where the Stone Golem hunt takes place. The Zombie enemies you encounter there are worth about 1,200 experience points apiece (with the Embroidered Tippet equipped, that will be doubled). Additionally, you’ll get chains of around 90 there. Just be sure to bring plenty of Eye Drops -- you’ll need 'em!
