Every event that can take Insane off a character. 2 events remove it directly. The rest replace it by granting the opposite. See Insane for what the trait does, or all traits.
Removal events 2
These take Insane off directly.
- Always Fair Weather rolled variant weight 2
- The Prophet's Rebuke rolled variant weight 1
A rolled variant is not a gamble. The game only offers the variant matching a trait the character has, so for a character whose only such trait is Insane, it is a targeted cure.
