This seems to be a common theme here, but I don't doubt the possibility that todays daily heroic has hidden things to be found. Every other secret mission found so far has involved either a raid or strike access point, and this daily might be no different. I've already killed the sisters on a normal mission for the grimoire, but what happens if you kill baxx and the cabal commander in the heroic? Or the sisters? Or Ir Yut who is magically alive again? Anyone find anything special on this level yet?
