Rebirth, considered the strongest technique of the entirety of {Spirit of the Phoenix}. Using the flame blessed onto the warrior by the Phoenix they use it to completely refine their body. Granting them a strength of which they could only dream of. This could only be performed once, and can only be properly executed a specific timeframe in a warrior's existence. If this was missed they could only relent for the rest of their lives.
Wrock had reached this point after the training with Tyin and Yomi. After being asked why he didn't undergo the process he gave a mysterious answer. However the actual reason was that he wasn't entirely sure it was possible.
In his previous world he had already undergone rebirth. Since it was the same Spirit from then he was unsure if it was possible. Moreover since what he had was an avatar and not his actual body it only deepened his doubts. Perhaps now that he properly executed it a weight was removed from his shoulders.
