What was changed into an immortal object?


In the first arc of _Sword Art Online_ (episode 14, ~9:40), the boss whom
Kirito fights activates something in a system console, and then a notice is
displayed: "Chaged[sic] into Immortal Object".

!["Chaged into Immortal Object"](https://i.stack.imgur.com/FxwhI.jpg)

However, this message does not seem to make sense. Despite Kirito's request,

> Asuna is slain by a one-hit KO as she attempts to defend him, and Kirito is
> consequently killed as well. His remaining consciousness then gives one more
> blow to Heathcliff, who dies. Thus, it is clear that none of these three
> characters was given immortal status.

Was this an error, in that the message was supposed to refer to this boss
_removing_ his own immortality? If not, what exactly did this message signify?




As you say yourself:

While googling, I came across some posts on [a
forum](http://forums.animesuki.com/showthread.php?t=115261&page=3) which seems
to say that it is a wrongly translated message and that it should say
something like: " _immortality status changed_ ".  
I'm not sure if it's accurate but it seems to tell the exact same thing.
