A Deep Dive into AD&D 2e Spells: Hypnotism

  • Level: 1
  • Range: 5 yards
  • Components: V, S
  • Duration: 1 round + 1 round/level
  • Casting Time: 1
  • Area of Effect: 30-foot cube
  • Saving Throw: Neg.

In the delicate art of magical manipulation, 1st-level spells often carry massive risks. Charm Person takes time and creates a permanent attachment, while Friends guarantees a hostile backlash. Hypnotism, however, is the surgical tool of the Enchanter. It briefly grants the wizard access to a 3rd-level effect—a Suggestion—without the target ever realizing their mind was tampered with. It is an espionage masterpiece disguised as a simple cantrip.

Functional Overview

Through a droning incantation and rhythmic gestures, the wizard lulls 1d6 creatures within a 30-foot cube into a highly susceptible trance.

  • The Suggestion: The affected targets become open to a “brief and reasonable sounding request.” This is a non-magical, vocalized urging given after the spell is cast.
  • The Language Barrier: Because the suggestion is a vocalized urging rather than a telepathic link, the wizard must speak a language the target understands.
  • The Saving Throw Modifiers: The spell’s saving throw is highly situational. Exceptionally wary or hostile creatures gain a +1 to +3 bonus to their save. However, if the wizard targets a single creature and meets its gaze, that creature suffers a -2 penalty to its save.
  • The Amnesia Clause: The most powerful sentence in the spell description: “A creature that fails its saving throw does not remember that the caster enspelled it.”

Tactical Insights & Exploits

A close reading of the mechanics reveals that Hypnotism operates less like a combat crowd-control spell and more like a high-stakes infiltration tool:

1. The “Poor Man’s Suggestion”

Gaining a Suggestion effect at 1st level is an incredible disruption of the standard spell hierarchy. The trick is understanding the word “reasonable.” You cannot tell a goblin to jump into a fire. However, telling a sleepy gate guard, “Your relief is here, take my silver and go get a drink at the tavern,” sounds entirely reasonable to a magically suggestible mind. The phrasing of the request dictates the success of the spell.

2. The Interrogation Hack (The Gaze Penalty)

While rolling 1d6 targets in a 30-foot cube is tempting, veteran players almost exclusively use the single-target gaze mechanic. Imposing a -2 penalty to a saving throw at 1st level is mathematically devastating. If the party captures a hostile lieutenant, tying them to a chair and forcing eye contact ensures the spell takes hold. The wizard can then simply “suggest” that it is in the lieutenant’s best interest to reveal the trap layout before the party’s fighter loses their temper.

3. The Amnesia Escape

The primary flaw of Friends is the social hangover—the moment the spell ends, the target knows they were manipulated. Hypnotism explicitly wipes the memory of the magical casting from those who fail their saves. To the target, the decision to abandon their post or hand over the keys felt entirely like their own logical conclusion. This allows a party to infiltrate and exfiltrate a noble’s manor without leaving a trail of magically violated, angry witnesses.

4. The “Blind Request” Gamble

The spell notes that the request must be given after the spell is cast, and until that time the success of the spell is unknown. If a wizard tries to hypnotize a group of three mercenaries, they don’t know who passed or failed their save until they give the command. If the wizard tells them to drop their weapons and only one is actually hypnotized, the other two will immediately attack. This makes area-of-effect casting highly volatile in combat situations.


Research & Acquisition

Hypnotism is a fundamental study of neurological manipulation and vocal cadence.

  • Research Time: 1d10 + 1 weeks.
  • Financial Investment: 100–1,000 gp.
  • Material Components: None (Verbal and Somatic only). The lack of material components makes it the perfect tool for a wizard who has been stripped of their gear and needs to manipulate a jailer.

Theoretical Variants

Enchanters frequently push this research to overcome the spell’s language and hostility limitations:

  • Telepathic Trance (Level 2 Research): Bypasses the spoken language requirement by projecting the “reasonable request” directly into the target’s mind. This allows the wizard to hypnotize bizarre aberrations, beasts, or humanoids whose languages they have not studied.
  • Deep Mesmerism (Level 2 Research): Rather than attempting to influence 1d6 targets, this variant focuses the magical energy entirely on a single target, increasing the gaze penalty from -2 to a crushing -4, making it nearly impossible for low-level NPCs to resist.
  • Triggered Command (Level 3 Research): The wizard implants the reasonable request, but it does not take effect immediately. Instead, the hypnotized target carries out the suggestion only when a specific word is spoken or an event occurs (e.g., “When the King raises his goblet, you will loudly announce there is an assassin in the room”).

The Verdict

Hypnotism is the ultimate finesse spell. It is useless against charging monsters or creatures you cannot communicate with, but in a city or an occupied dungeon, it is unparalleled. By weaponizing the -2 gaze penalty and exploiting the amnesia clause, a clever wizard can dismantle encounters through dialogue rather than fireball, leaving no evidence of their presence behind.
