The Radiant Stone is bright, glowing cube on the Sunstone Isle in Matumada. The Radiant Stone's heat will damage players the closer they get to it, quickly killing even the most armored adventurers who pass too close to it. It is advised to take caution when near this landmark.
The Radiant Stone has a secret feature that originally went unnoticed to the community. When one stands at least close enough to the cube to be able to reach out and touch its aura for an approximate 20 seconds, they will be given a random, yellow-themed item. This can be achieved by consuming large amounts of food to survive the time. The possible rewards can be found below:
- Right after the Spring Update was released, the Radiant Stone had been a focus of many experimenter and secret-hunters due to the mysteriousness of the object.
- Standing on the edge of the damage zone will not allow you to gain an item after the 20 second timer, as you have to be closer to the aura.
