As far as Rain's understanding about Morpheus Online went, the Inspection skill would either work or fail.
There was no in between.
But using it on Grey Watcher had somehow worked, despite the fact that it had failed earlier. Of course, he still couldn't see any important information, but it was still enough for him to be shocked.
'I knew when the skill failed that his level was high, but how can he change the thing? Is there an option to do that?' Rain first wondered if this was a default game feature.
Which this was not.
Arthur was able to do this due to the fact that he was using his disguise skill. The veil of Thousand Skins allowed one to change how information was displayed to the others.
Of course, this was restricted by the level and was fixed for the day once the skill was used. But one could still allow the skill to show a part of the information of if they wished to do so.
