Loads of Exp early on
Get the Jewel Knuckles (with the hint below) and go to the holy chapel. Go up the large set of stairs and enter the room with the Spectral Sword (two rooms after). Then go back to the stairs and go to the spiked ball. These are hard to kill with normal weapons but there is a trick you can do with the Jewel Knuckles. Equip them and crouch close to the ball. Hold attack and keep holding it. The ball should be repetedly stricken with the Knuckles even though the animation has stopped. You will also get a few Critical hits which will make this quicker.
