After the first 10 floor one I have a decent amount of the hero gear- mostly notable for Tifa, but some of the others let me clear up inventory /dust off a few others (I totally forgot I had Tellah's earth chain, for example). The drop rewards were mixed, I did get a 6* mote (as in 1) and some crystals.


Also rather convenient for Magia, especially if you have somebody with instant turns and/or AOE.
