The Find Recruits II quest used to give a golden troop summon token at the end.
I have just completed it and got nothing (I mean, I did not need the recruits, I was only going for the token) -wasting 24 of my energy points for 40 out of the 100 monsters I needed for the monster chest, when with 24 energy points I could have filled the monster chest on 7-4 or 8-7.
