Laboratory Keycard Class Authority is required to access Vanadis Laboratory [Lv:2], where Valaris can be found. This is the process that needs to be done:

  1. Walk to the toppest part of the map. Go to the middle of it.
  2. Talk to the Hidden Door. It will give you a quest to find the keycard.
  3. Keep killing Infected Eremes until you get it.

Do note that this is a 'special drop', so it is not affected by Bubble Gum. The chance of getting this item is random.
