Necropolis discussions.

In general, good day to everyone.
I'm interested in how effective the "steal arrows" ability of ghosts is, or if it's effective at all. How often is it used?

Personally, I never use it (so if I do upgrade it, it's for the specters; most often I leave it unupgraded - it doesn't affect the chance to miss anyway);
most of the people I know - almost never;
as for the rest - it's a matter of taste, as they say...
