I looted a Goodie location and found Throwing Daggers - lets the Hero throw daggers at enemies up to 3 squares away.
So I equipped it (Icon turned green) with my champion but during combat there's no skill / ability button to throw daggers.
I tried it on my other champions as well to no avail.
Then an air elemental ate my party
(those may say 'weak' in the status but don't believe it)
