So where is the errata to this very stupid and biased decision to not allow Investigators to use wands?
Might I also suggest (for face saving of the developer who "may" have made such an ill-thought out statement)that at third level the ability be granted.
I really think the only reason this is the way it is, is that a developer made a quick statement without thinking and the players now pay the cost of the refusal to admit it was a mistake.
