Henceforth, it will be more difficult for a character to use "Detect Evil" to determine whether an individual is evil. The detector must place his/her hand on the target and concentrate for a few seconds. The detection is automatic if the target is willing but there will be a DC if the target is attempting to mask the evil within.

The purpose of Detect Evil is not to cut through the intrigue of player interaction, but rather to allow the paladin to strike with impunity against certain monsters and obvious enemies. Thus, the paladin can still use this ability to participate in offensive actions in locales which are clearly dominated by evil characters and monsters.
