After you complete the "Donate to the Temple of Light" quest and receive the Rising Sun Legendary Cleaver, leave the temple and go back towards Oakfield. When you get to the split in the path where you can go over the small bridge to the right to travel to Oakfield, stay left and follow the path up the small hill towards the ruins at the top of the hill. When you get to the ruins, to the left is the entrance to the Wellspring Cave. Enter the cave then turn around and leave. When you get done loading the outside, you will receive another Rising Sun. Do this as many times as desired for money or to be used as gifts.
