Of course. The library is simple, rush to the inside, then pull it out, go in and try to avoid monsters and reduce blood loss. If the armory is finally pulled by the boss, be very careful when you go in. Kill the monster who first saw you. If you don't pull, just rush. My boss of 4400DK usually pulls, so you should take advantage of his illness and infection, and then get some blood from the spiritual world.

If you take Ben with you, you will be familiar with it after running a few more times.
