Yes, Lucky Charm is terrible.
Same for Loremaster, that is a tactical combat ability, the identifying stuff is a side effect.
If mob examination is removed from Loremaster, it can be turned into an aura.
I don't understand. If the enemy examination is removed, then what's the point of an aura? You can identify any item from any character's inventory as long as one of the party has the appropriate Loremaster rank and a magnifying glass.
Though I will add that it's silly to restrict monster examination to the character who actually has Loremaster, because it doesn't actually provide any character bonus. It's meta information that helps the PLAYER, not the character, so as long as I have a character with the appropriate skill, I as the player should always have access to the information, no matter whose turn it is.
