Confusion

Confusion, the state of being confused, is a condition of your character. Experienced NetHack players know that they can use confusion to alter the effects of magical items, such as scrolls.

In Hack, bats could cause confusion. NetHack has now differentiated this so that stun and confusion are not the same. Bats and trapped doors can stun you; this causes you to move in random directions, like confusion would. However, only confusion will let you level-teleport with an uncursed scroll of teleport.

For advanced characters, the easy way to control confusion is to:
 * Begin confusion by trying to cast a forgotten spell.
 * End confusion by applying a (not cursed) unicorn horn.
