Okay. If it was explicitly shown, I won't argue further, but it seem uncertain if it retained its raw power or not.
Regardless, Thor empowered the Celestial-killing spell (which didn't make any sense, as even th Odinsword did not display that degree of power against the Celestials), and the power of the Hulk and the Sentry combined were also sufficient to halt the descent of Exitar to the Earth within that storyline, if I remember correctly, and giant versions of Iron Man, Thor, She-Hulk, and Ghost Rider were still able to efficiently fight Celestials in a more recent Avengers story, so my point that they have been very inconsistent remains.
