After watching the scene, Nameless understood.
He conjured a staff out of thin air and set the gem into it. When he activated the gem, green light formed a protective barrier.
This was the "Light of Protection" mentioned in the Appraisal.
The Light of Protection came from a sense of security. Simply put, the more secure its holder felt, the more powerful it became.
The problem was that a sense of security could not be measured. When facing an attack, the holder could hardly be certain the Light of Protection would stop it. The less certain they felt, the less secure they became, creating a vicious cycle.
As far as Nameless knew, female Mountain-Bearing Horned Leopard Beasts did grow a gem on their foreheads during pregnancy, and those gems did provide some defense.
But that defensive power was tied to the beast's own level.
In other words, although this emerald looked exactly like one grown on the forehead of a female Mountain-Bearing Horned Leopard Beast, it was actually the embodiment of that particular beast's sense of security.
The two gems' supernatural powers were entirely different.
Nameless teleported the staff to the warehouse, then returned to the Bubble Exoshell's interior.
He now understood another side of the Dream World, but he did not intend to spend much time searching for Top-Tier Mutated Beasts or plundering their Dream Treasures.

If Nameless did not fear an attack to begin with, having the gem made no difference.
And if he did fear an attack, he
