The Eastern Crystal Pylon is located in Un'Goro Crater.
A closer inspection of the pylon leads you to find a small table containing blue, yellow, and green crystals arranged in what seems like a specific formation.
A large blue circle of crystals is flanked on either side by a smaller circle of yellow crystals and another of green crystals.
You carefully take note of the colours of the crystals, knowing that J. D. would be very interested in hearing about what you have found.
The Eastern Pylon accepts blue, yellow, and green crystals.
It focuses on the energy that can be created using blue crystals as the main source of power. There are two possible effects: one provides bonus to spirit, and one that creates a damaging shield.
The Crystal Pylons of Un'Goro are a mystery to all. To the few inhabitants here, they are a source of legend, with much speculation as to their purpose.
