Sanity

'The Sanity''' icon is an in-game measure of player character's sanity, expressed as a numerical value. Players can gain and lose sanity in various ways, and reaching 0 results in Total Insanity. At this point, the brain icon will be completely shriveled.

A small animated arrow appears in front of the brain, showing when sanity is increasing or decreasing. A bigger arrow means that your sanity is increasing/decreasing faster. As sanity decreases, strange things start to happen: the player's vision becomes shaky, over-saturated, and bright, whispers are heard, and shadowy monsters (called Hallucinations) start to appear. When one reaches <30 sanity, the hallucinations start to attack.

Generally, doing unusual or scary things will decrease sanity. Doing fun, spontaneous, and interesting things will increase sanity.

Due to the fact that several magical items decrease sanity when used, it could be thought of as a sort of mana that is depleted by magic use. However, having little sanity brings about its own benefits (for example getting nightmare fuel for powerful weapons and armor.)
