Dementia

Your grip on reality starts to slip as your mind is muddled.
  Dementia is a worse version of Bewilderment that can be permanent.
  For each point of Dementia, choose one skill from the following list. You automatically fail any Check or Save using that skill because your perceived reality is incorrect.
    • Perception. Everything you see, hear, and smell around you is twisted into something it is not.
    • Insight. Everything others do is twisted to fit your warped perspective.
    • Focus. Your mind wanders from topic to topic.
    • All knowledge skills. Your memories are confused and tangled.
    • Attack Rolls and Casting Checks. You have trouble remembering how and why to cast or attack.
    • Everything. You cannot meaningfully perceive the world around you. You are effectively Incapacitated.

 

Recovery

When you complete a Night's Rest while having any Dementia, make a Focus Save with DC 10 + Dementia. If you succeed, one point of Dementia is healed. If you fail, one level of Dementia of your choice becomes permanent.
  Some powerful magic can clear Dementia from the mind.
