No Lock

 

A locked wooden door is here.

Magical Trap

The door itself is not actually locked and just slightly stuck. The lock on the door is an illusion. It has no DC to open, any attempt will appear to give a satisfying click and succeed. However, the door won’t open. The door can be pushed open with a DC 18 Strength check. A spell or other effect that can sense the presence of magic, such as Detect Magic, reveals an aura of illusion on the lock. A spell such as Dispel Magic will cause the lock to disappear. Any effect that suppresses magic will make the lock vanish for the duration of the effect.

 

Blow Dart Chest

 

A large wooden chest sits in the corner.

Mechanical Trap

The chest has an air bladder operated blow gun inside. There are 4 small screws on the top of the lid near the back. A DC 14 Intelligence (Investigation) check suggests that these screws have no obvious function. A DC 14 Dexterity check with thieves’ tools is required to open the box. When the box is opened, the lid pushes an air bladder which fires a poison dart with a +4 melee attack for 1d4 hp of piercing damage. On a successful hit, the stricken creature must make a DC 14 Constitution saving throw or fall asleep for 1d4+1 hours. After one hour, the sleeping creature may be awoken normally. However, before then, the creature can only be awakened by either a DC 15 Medicine check or magical healing. The trap can be avoided by opening the box from behind. It can be disabled by unscrewing the 4 small screws.

 

Slippery Doorknob

 

Sharp edges protrude from the doorknob.

Magical Trap

The edges on the doorknob cut deeply if one is not careful. However, the doorknob becomes greased when used. Although there are several sharp edges on the doorknob, it looks as if one could carefully open it. However, when touched, the doorknob becomes covered in grease for 1 minute. A DC 14 Dexterity check is required to open the door, otherwise the creature takes 1d4 slashing damage. If the grease is present, this check is at disadvantage. A spell or other effect that can sense the presence of magic, such as Detect Magic, reveals an aura of conjuration on the doorknob. A spell such as Dispel Magic will neutralize the doorknob. Any effect that suppresses magic will keep the doorknob from being greased for the duration of the effect.

 

Itchy Door

 

A dusty wooden door is closed again.

Mechanical Trap

The dust in the door causes skin irritation. The door is locked and requires a DC 15 Dexterity check with thieves’ tools to open. Otherwise it has AC 15 and 15 hp or can be broken with a DC 18 Strength check. If the door is opened normally, a small dust puff is emitted from the door. The creature opening the door must make a DC 12 Constitution saving throw or become itchy for 1 hour. If the door is broken open, a large dust cloud appears. All creatures within 15 feet must make a DC 14 Constitution saving throw or become itchy for 1 hour. Itchy creatures receive disadvantage on all skill checks and attack rolls. The trap can be disabled by covering it in a cloth before opening it. If the door is destroyed, the cloth will limit the cloud to 5 feet.

 

The Dead Garden

 

A lush, colorful garden is very out of place in this desert. In the middle a marble mermaid fountain holds a dazzling gem.

Magical Trap

The gem protects this small oasis. Removing it removes the protection. The gem appears to be a fist sized diamond. If it is removed, the gem crumbles and the garden immediately withers and dies. Every living creature in the garden takes 12d8 necrotic damage. A DC 18 Constitution saving throw reduces this by half. A spell or other effect that can sense the presence of magic, such as Detect Magic, reveals an aura of abjuration on the gem. A spell such as Dispel Magic with a spellcasting DC of 18 will neutralize the gem, setting off the trap, and destroying the gem. Any effect that suppresses magic of spell level 8 or higher will also set off the trap. However, when the suppression ends, the garden will regrow in 1d6+1 weeks; the gem will become dull during this time, but will not be destroyed.

 

Round Room

 

A circular door is on the wall.

Mechanical Trap

The circular door leads to a small, cylindrical room that is balanced on a fulcrum. The door opens into a 10′ diameter cylindrical room that is also 10′ long. A second round door is other side. A DC 16 Wisdom (Perception) check reveals that there is a small air gap between the door and the cylindrical room. Stepping into the room causes the cylinder to unbalance. The creature stepping into the room must make a DC 16 Dexterity saving throw or the room rolls down the side of the fulcrum. On a successful save, the creature jumps back out of the room. On failure, the creature takes 6d6 bludgeoning damage. The two doors remain, only the cylinder rolls down the incline. The trap can be disabled by physically bracing it from an open door. This requires a DC 16 Strength check.

 

Trompe L’oeil Stairs

 

A seemingly uneven staircase leads downwards.

Mechanical Trap

The staircase is actually perfectly level but has been painted to depict the stairs unevenly. A DC 12 Wisdom (Insight) check reveals that the uneven stairs are a clever illusion that has been painted on and also grants advantage on the Dexterity (Acrobatics) check when descended the staircase. Any creature using the staircase must make a DC 12 Dexterity (Acrobatics) check or lose their balance and fall, taking 2d6 falling damage. The trap can be neutralized disrupting the optical illusion. This can be as drastic as using paint remover on the stairs to something as simple as placing a cloak on the stairs.

 

Big Lock

 

The chest is secured by a sturdy iron lock.

Magical Trap

The lock is enchanted to enlarge anything that goes into it, except it’s own special key. The lock requires a DC 14 Dexterity check with thieves’ tools to open. However, any object that enters the lock must make a DC 12 Constitution saving throw or double in size. If the object is something like thieves’ tools, failure also means that the object is destroyed and is wedged in the lock until it shrinks back to normal size in 1 minute. A spell or other effect that can sense the presence of magic, such as Detect Magic, reveals an aura of transmutation. A spell such as Dispel Magic will neutralize the lock permanently, while any effect that suppresses magic will neutralize the enlarge effect for the duration.

 

Screw Door

 

Stairs lead up to a revolving door.

Mechanical Trap

The revolving door is actually a screw that secures the stairs to the ceiling. Threads at the top of the door can be seen with a DC 16 Wisdom (Perception) check. A DC 14 Intelligence (Investigation) check can determine that passing through the door by rotating it counter-clockwise unscrews the door, while simply rotating the door clockwise tightens the screw. After the door is used 3 times, the screw comes out of the ceiling, collapsing the staircase. Creatures on the staircase take 1d6 falling damage and 2d6 bludgeoning damage. The trap can be neutralized by simply rotating the door clockwise after each time it is used.

 

Missile Arch

 

A brick archway leads on.

Magical Trap

A magic missile shoots out of the arch at anyone who passes through it. Anytime a creature passes through the arch, it glows red and fires a missile of force at it that automatically hits for 1d4+1 damage. A spell or other effect that can sense the presence of magic, such as Detect Magic, reveals an aura of evocation. A spell such as Dispel Magic will neutralize the arch permanently, while any effect that suppresses magic will cause the arch to cease shooting missile for the duration of the effect.
