This is a spell which discovers emanations of evil, or of good in the case of the reverse spell, from any creature or object. For example, evil alignment or an evilly cursed object will radiate evil, but a hidden trap or an unintelligent viper will not. The duration of a detect evil (or detect good) spell is 1 turn + 1/2 turn (5 rounds, or 5 minutes) per level of the cleric. Thus a cleric of Ist level of experience can cast a spell with a 1 1/2 turn duration, at 2nd level a 2 turn duration, 2 1/2 at 3rd, etc. The spell has a path of detection 1” wide in the direction in which the cleric is facing. It requires the use of the cleric’s holy (or unholy) symbol as its material component, with the cleric holding it before him or her.
