Madness can be short-term, long-term, or indefinite. Most relatively mundane effects impose short-term madness, which lasts for just a few minutes. More horrific effects or cumulative effects can result in long-term or indefinite madness.

A character afflicted with short-term madness is subjected to an effect from the Short-Term Madness table for 1d10 minutes.

A character afflicted with long-term madness is subjected to an effect from the Long-Term Madness table for 1d10 × 10 hours.

A character afflicted with indefinite madness gains a new character flaw from the Indefinite Madness table that lasts until cured.
