So had decided to play lumen a bit again, saw this map and got into it. Had done a good bit till I had gotten the 1st crystal, wtf do I do with it? Had tried explosions, grinder, shoving it into other stuff, shoving them into each other, explosions while they are grouped, and lasers. Right now I just have a pile of crystals in a corner with no idea what to do with em. Also do the armored box's never break in the grinders? Had 1 being grinded for almost 10 mins.
