Decoding the Arcane: Magic Mouth & Glyph of Warding
The combination of the Magic Mouth and Glyph of Warding spells allows for a deceptively simple yet potentially complex magical trap. Essentially, you use Magic Mouth to create a trigger mechanism for Glyph of Warding. The Magic Mouth spell creates an illusory mouth on an object that can speak a pre-determined message when a specific condition is met. This condition, then, becomes the trigger for the Glyph of Warding. This combination creates a situation where simply hearing or seeing something can unleash the ward’s magical effect. This is a creative use of the two spells that can create unique outcomes.
Understanding the Spells Individually
Before diving into the combined usage, it’s crucial to understand each spell’s capabilities and limitations.
Magic Mouth: The Whispering Ward
Magic Mouth is a 1st-level illusion spell. It allows you to implant a message within an object that isn’t being worn or carried. This message is triggered by a condition you set when casting the spell.
- Functionality: Creates an illusory mouth on an object that speaks a pre-determined message when a specific condition is met.
- Limitations:
- Cannot distinguish invisible creatures, alignments, level, HD, or class except by external garb.
- Range limit of a trigger is 15 feet per caster level.
- Responds only to visible or audible triggers and actions in line of sight or within hearing distance.
- The object speaks the words – you are not casting a spell through it.
Glyph of Warding: The Hidden Harm
Glyph of Warding is a 3rd-level abjuration spell. It allows you to inscribe a glyph that harms other creatures, either upon a surface or within an object.
- Functionality: Inscribes a glyph that triggers a harmful magical effect when a specific condition is met.
- Types of Glyphs:
- Spell Glyph: Stores a prepared spell of 3rd level or lower.
- Explosive Glyph: Deals 5d8 acid, cold, fire, lightning, or thunder damage.
- Limitations:
- The spell in a Spell Glyph must target a single creature or an area.
- Requires two spell slots: one for Glyph of Warding and one for the stored spell.
- The glyph is considered a magic trap, making it hard to detect and disable.
Combining Magic Mouth and Glyph of Warding
The cleverness of using Magic Mouth with Glyph of Warding lies in its ability to create less obvious triggers.
- Casting Magic Mouth: You cast Magic Mouth on an object, setting a trigger such as “when someone says the word ‘banana’.” The mouth is then programmed to say, “The coast is clear!”.
- Casting Glyph of Warding: You cast Glyph of Warding on the same object (or nearby, depending on your setup), setting the trigger as “when the phrase ‘The coast is clear!’ is spoken.”
- The Trap is Set: Now, when someone unknowingly says the word “banana,” the Magic Mouth activates, speaking the trigger phrase, which in turn activates the Glyph of Warding.
Advantages of this Combination
- Indirect Trigger: Masks the true trigger, making it harder for enemies to anticipate the trap.
- Verbal Triggers: Allows for triggers based on speech, expanding the possibilities beyond physical interactions.
- Customizable Complexity: The Magic Mouth trigger can be as simple or complex as you desire, adding layers of security.
Potential Uses
- Alarm Systems: A Magic Mouth could be placed near a door, triggered by footsteps, and then activate a Glyph of Warding storing Hold Person to trap intruders.
- Hidden Defenses: A Magic Mouth hidden in a book could be triggered by someone reading a specific passage, unleashing a Glyph of Warding with a damaging spell.
- Deceptive Traps: A seemingly harmless object could trigger a devastating Glyph of Warding when interacted with in a specific way, based on the Magic Mouth‘s parameters.
Limitations and Considerations
While powerful, this combination has limitations:
- Spell Slots: Requires two spell slots, making it a resource-intensive trap.
- Material Components: Both spells require material components, adding to the cost.
- Detection: Glyph of Warding can be detected by spells like Detect Magic, though it might be harder if drawn on a large surface.
- Counterspells: You cannot use your reaction to counterspell a spell that activated when a Glyph of Warding is triggered.
Frequently Asked Questions (FAQs)
1. Can you put a healing spell on a Glyph of Warding?
No, Glyph of Warding only accepts hostile spells. Only the hostile part of a spell like Heal would function. The spell in a Spell Glyph must target a single creature or an area.
2. Can you cast spells with Magic Mouth?
No, you cannot cast spells through Magic Mouth. Magic Mouth simply speaks a pre-determined message. The object itself speaks the words, not you casting a spell.
3. Does Counterspell work on a Glyph of Warding?
No, you cannot use your reaction to counterspell a spell that activated when a Glyph of Warding is triggered. This is because Counterspell requires you to see the creature casting the spell within 60 feet, which is not the case with a triggered glyph.
4. Can you stack Glyphs of Warding?
Yes, there is no explicit rule preventing you from stacking Glyphs of Warding on a single object/surface. However, consider the resource cost (spell slots and components) and the potential for overkill.
5. Is a Glyph of Warding a trap?
Yes, a Glyph of Warding is considered a magic trap. A rogue (only) can use the Search skill to find the glyph and Disable Device to thwart it.
6. Can Detect Magic see Glyphs of Warding?
Yes, Detect Magic can detect Glyphs of Warding. However, it becomes MUCH harder to rule if the Glyph is drawn on a larger, continuous surface like the ground, as this is not considered an object under the rules.
7. What happens if Mage Hand triggers a Glyph of Warding?
If a creature uses Mage Hand to open a container with a Glyph of Warding, the glyph activates if the trigger conditions are met. If the glyph stores a spell that targets a creature, the Mage Hand‘s controller becomes the target.
8. Can you put Wish in a Glyph of Warding?
Theoretically, yes. If you can cast Wish at the same time as Glyph of Warding then it would be stored.
9. Can you Counterspell Beholder eye rays?
No, Counterspell cannot be used on beholder eye rays. Beholder eye rays are magical effects but are not spells, and Counterspell only works on spells being cast.
10. What spell is similar to Glyph of Warding?
Contingency is a spell that is similar to Glyph of Warding. This is because you can specify certain criteria which will trigger the spell to be cast on yourself that is of 5th level or lower.
11. Can you use Glyph of Warding on a weapon?
Yes, you can put a warding glyph on a weapon, and more specifically one that activates on an enemy you are attacking. However, the stored spell must target a single creature or an area, so you couldn’t use it to imbue the weapon with a spell like Holy Weapon.
12. Can you put Glyph of Warding on a creature?
No, you cannot cast Glyph of Warding on a creature directly. The spell requires inscribing a glyph on a surface or within an object.
13. Can a Magic Mouth distinguish invisible creatures?
No, a Magic Mouth cannot distinguish invisible creatures or detect creatures through magical disguises, unless the disguise provides audible or visible clues.
14. How close do Magic Mouth and Glyph of Warding need to be to work together?
The distance depends on the trigger range of the Magic Mouth, which is 15 feet per caster level. The Glyph of Warding needs to be within that range to be triggered by the Magic Mouth‘s activation.
15. Could I use Magic Mouth to create a password system for my Glyph of Warding?
Absolutely! You could set the Magic Mouth to only speak the correct trigger phrase for the Glyph of Warding when the correct password is spoken. This adds an extra layer of security to your magical trap.
Beyond the Basics: Creative Applications
The combined power of Magic Mouth and Glyph of Warding extends far beyond simple traps. Imagine a complex series of Magic Mouth relays, each triggered by the previous one, leading to a final Glyph of Warding that unleashes a devastating spell. You could create intricate puzzles where solving them involves speaking the right words to trigger the Magic Mouth sequence, rewarding clever players while punishing those who blunder. The possibilities are as limited as your imagination, but understanding the rules of the game is key to mastering its potential, which is why resources like the Games Learning Society can be so valuable.
