The Iron Empyrean Tentacle was an Iron Grade Pranic Beast. And thanks to its Primary Nature of Daily Checkpoint, it was extremely prone to mutations.
The Silver Empyrean Tentacle, on the other hand, wasn't prone for mutations at all.
Primary Nature—Prana Solidification!
It gave the Silver Empyrean Tentacle a strong resistance towards mutations as its Prana would constantly revert it to its optimal state. But eventually, it mutated to become a Free Human, not voluntarily, but was forced to do so by the Gold Empyrean Tentacle that constantly targeted it first.
And every single time they fought, the Silver Empyrean Tentacle lost, by the end of which it was forced to flee.
Prana Solidification allowed it to create constructs of Prana, using which it could traverse the place without issues. And back in the days, there was no Influenced Region of Hidden Eye.
