The Fuse is located through the third door. Use the Tape Recorder through the second door to get the Elder Knowledge trait. Go down to Floor B2, and use the keycard to unlock the door. After your first teleport, a keycard will appear on a nearby table. This can be done at the start of the game. Lumenite Crystals can also upgrade your Dragon Heart charges. Boss weapons are special weapons that drop from bosses, and can be acquired by defeating bosses using alternate methods. Elite enemies are much more likely to spawn, regular enemies will be more difficult, and Lumenite Crystals will drop more commonly. Rerolling will reset the world and make it much more difficult. You will then have the option to increase the difficulty and Reroll at this location.

Once the final boss is defeated, return to Ward 13 and activate the Red Stone. Successfully complete the story and defeat the final boss.
