Near the town of Bruna, go east, then southeast. If you reach The Red Ruby Cave you went too far. You will need to go back west slightly. You should see a shrine, that once activated, will give you Conjuration points as well as a temporary bound weapon and/or greaves. You can keep activating the shrine every 24 hours. Wait in front of it for 24 hours, then activate it again. Repeat this as many times as desired.
