Mental
Healthy
You are healthy and cured.
Latent
The victim can pass on contagious diseases but suffers no ill effects.
Weakened
The victim is shaken, and the DCs of his spells and special abilities decrease by 2. He can no longer cast his highest level of spells (if any).
Impaired
The victim is flat-footed and no longer adds his mental ability score modifiers when calculating number of uses per day of abilities dependent on those scores, including bonus spells per day. The DCs of his spells and special abilities decrease by an additional 2. He can no longer cast his 2 highest levels of spells (if any).
Befuddled
The victim begins losing his grasp on thought, reality, and self. He has a 50% chance each round to take no relevant actions, instead babbling randomly, wandering off, or talking to unseen parties.
Disassociated
The victim is almost entirely disconnected from reality. His mind filters and twists all external stimuli into strange forms. He can no longer tell friend from foe and can’t willingly accept any aid (including healing) from another creature unless he succeeds at a Will save against the disease’s DC.
Comatose
A victim rendered comatose by a mental disease has lost all grip on reality and entered a dream world. He can’t be woken.
Dead
The victim is dead, and his corpse may still be contagious.
