As you play through the mission entitled "," you'll encounter a new kind of puzzle characterized by breakable blood crystals. If you chose to go to Treviso before Dock Town, this is the first time you'll see puzzles of this sort. These crystals effectively function as a magical power source, usually serving to keep an impenetrable wall between nosy interlopers and whatever a blood mage wants to keep secure. Thankfully, the grand majority of them are pretty straightforward — until a certain point in the quest, that is.
During this particular quest, several blood crystals must be broken to create a path to Lucanis. However, it's an optional area — the High Security room — that provides the hardest iteration of this puzzle. You'll enter, shortly after freeing Lucanis, to find a series of barriers that scarcely conceal three rooms full of loot, and a very obvious crystal presiding over it all.

The trick to discovering the right order in which to break them is to follow the shimmering crimson line emanating from the shielded one.

For the High Security room in particular, though, that line is difficult to see because of the distance between Rook and the shielded crystal, and the sneaky hiding place of the unshielded one that must be shot at first. The unshielded crystal is located on the exact opposite side
