Deadly Trap (Levels 1–4)

Trigger: A creature moves onto a pressure plate
Duration: Instantaneous, and the trap resets at the start of the next turn

When a creature moves onto this trap’s pressure plate for the first time on a turn or starts its turn there, a nearby statue exhales a 15-foot Cone of magical flame. The statue can look like anything, such as a dragon or a wizard. Each creature in the Cone must succeed on a DC 15 Dexterity saving throw, taking 11 (2d10) Fire damage on a failed save or half as much damage on a successful one.

Detect and Disarm. A Detect Magic spell reveals an aura of Evocation magic around the statue. As a Search action, a creature within 5 feet of the statue can examine it and make a DC 10 Wisdom (Perception) check, detecting a tiny glyph on the statue on a successful check. Once the glyph is found, a character can take a Study action to examine it and make a DC 15 Intelligence (Arcana) check, ascertaining that the glyph means “fire” on a successful check. As an action, a character can use a sharp tool to deface the glyph, which disarms the trap.

As a Search action, a creature can examine the section of floor that forms the pressure plate and make a DC 15 Wisdom (Perception) check, detecting the pressure plate on a successful check. Wedging an Iron Spike or similar object under the pressure plate prevents the trap from triggering.

At Higher Levels. You can scale the trap for higher levels by increasing the damage and the area of effect, as shown in the following table.

Levels   Fire Damage   Area of Effect
5–10 22 (4d10)
30-foot Cone
11–16 55 (10d10)
60-foot Cone
