@Gsi (from two days)

That's what I had meant, because there were both OSSs in my reply. And the thread had an error of not showing my message until later...

Arms Blast, etc. are not system-enhanced skills. The skill where Kirito used to break Kuradeel's sword was indeed the Sword Skill «Sonic Leap», but there was a deliberate targetting of a certain part of Kuradeel's sword rather than fighting the «Avalanche» Skill head on.

As for Immortal Objects, while the Light Novel and Anime do depict the «Immortal Object» reprimand while also showing characters "breaking the environment" (stabbing swords into the ground, etc [there was also one instance in SAO with Coper and his Small Sword sticking upright in the ground]), the interaction with the "Immortal Surroundings" could show that the environment could sustain damage, but be repaired with a split second notice. We could compare this instance to the (Alicization Spoiler-ish) brief destruction of the Central Cathedral's wall, but it was almost immediately repaired by the system. Then following that, Kirito was able to stick pitons (large needle thing-majigs) into the Central Cathedral's wall. The Cathedral would then repair itself when the pitons disappeared, as the pitons would not have replaced the "matter" that occupied the Cathedral's wall.

So, in this case, it's not a matter of "Immortal Objects being dealt damage" but rather the "retaining of the Immortal Object's form." It may seem a bit far-fetched, but this is one of the few explanations I can give.

I believe that «Immortal Objects» do have a set Durability value, but it is either too high to deplete with any one action or rather than being attuned with the effect of "loss of Durability over time," it has a "regeneration of Durability over time." With all of the context we are gleaning from the Light Novel, I wish to believe the latter («regeneration of Durability over time»).
