Wanted: Medical Supplies

Walkthrough

 * Talk to Yasuji (A) at Conflux #3.
 * Open a blue Sturdy Pyxis to get the key item. you must open it within 3 tries or more.
 * If you open the chest using a Forbidden Key you won't get the key item. You need to open that by guessing game.
 * A chest obtained with capped Azure lights seems to have more chance to drop the key item. Probably, blue chests scattered around in the area won't work, you need to drop them from monsters. (Based on what?)
