Key always spawns around the boss area and it can be above or below in other areas. It was likely to the south east or north close by the Sandman in the first Act. Some crystal camps you can get enemies to break them so you don't have to waste time dealing with them and can go for another objective. edit: Also Melusine kinda has a double dash in that she will move quickly after breaking Sing Stance and you can then use your dash to create more distance.
I’ll keep that in mind for the next run for the key. I know the lightning jinn or wizard does a ton of damage to the dream shard crystals so I end up using those enemies to break crystals for me.
