The Dark Isle Crystal

Radiant Blood Walk Through

1. Speak to Rafin bin Fezesh to get a Crystal of Perception and then head to Dark Isle.
2. You must now run to three locations on the island and use your crystal:
   1. Run to 86.9N, 59.8E and use the Rock
   2. Run to 96.4N, 54.6E, run to the top of the ice tower, and use the Rock

You take the small crystal that was given to you and slowly pass it over the stone. The crystal glows blue briefly, then stops. You feel a warm sensation pass over your skin, followed by a chill. You think that the crystal might have done something to you, but you're not sure what.
