“If you don’t control yourself, someone else will.”
Detect Affect (Arcane)
Range: 120 feet
This arcane spell allows the caster to determine what type of magical control or influence a single person or creature is under, such as Charm spells, magical hypnosis or various other forms of affecting others and controlling their wills. As a wizard progresses, their ability to work this spell changes as follows:
Levels 1-2, Magic-User can determine the exact nature of this spell.
Levels 3-5, Spellcaster also knows who has cast this controlling spell and when the influence began.
Levels 6+, Wizard can also attempt to dispel this magical control, this functions on a percentage as Dispel Magic (See S&W Core Rules, 2nd printing, page 37*) and in addition causes 3d4 damage to the mage who cast the influencing spell and reveals their location in the wizard’s mind.
*Follows is a quote from the Core Swords & Wizardry book for quick reference:
The chance of successfully dispelling magic is a percentage based on the ratio of the level of the magic-user trying to dispel over the level of the magic user (or HD of the monster) who cast the original magic. Thus, a 6th level magic user attempting to dispel a charm cast by a 12th level magic-user has a 50% chance of success (6/12 = 1/2, or, 50%). If the 12th level magic user were dispelling the 6th level magic-user’s charm, the chance would be 200% (12/6 = 2, or, 200%).
