How does one know? That this, supposed "high level" mage,... can not see invisible/stealthed objects/persons. Kinda makes one wonder how he got the position,... or might he just so happen to be a "paper" Mage, only mage by the piece of paper on the wall, that since in reality, he is completely incompetent. if this be an oversight, might want to, ahem, fix this inconsistency.
