Artifact pair of lenses that temporarily increases Intelligence when worn, but permanently decreases Intelligence each time you remove them.

Artifact unaligned pair of lenses The Lens of Truth (or Lenses to avoid oddity), from Zelda, which grants see invisible when worn. Also, while wearing them, you must tell the truth, which primarily affects interacting with vault guards and could be implemented as any of the following:

• You will auto-reply to vault guards with your real name rather than being given the opportunity to lie.
• You are prompted “Give your name?” so you can remain silent.
• You are penalized for lying, much more harshly than losing an alignment point.

Option to configure your character to be nearsighted, which prevents you from seeing things more than a few spaces away from you unless you’re wearing lenses. You can also be farsighted, which means you can’t read scrolls or spellbook unless you’re wearing lenses.
