Falling Net

Mechanical trap

This trap uses a trip wire to release a net suspended from the ceiling. The trip wire is 3 inches off the ground and stretches between two columns or trees. The net is hidden by cobwebs or foliage. The DC to spot the trip wire and net is 10. A successful DC 15 Dexterity check using thieves’ tools breaks the trip wire harmlessly. A character without thieves’ tools can attempt this check with disadvantage using any edged weapon or edged tool. On a failed check, the trap triggers. When the trap is triggered, the net is released, covering a 10-foot-square area. Those in the area are trapped under the net and restrained, and those that fail a DC 10 Strength saving throw are also knocked prone. A creature can use its action to make a DC 10 Strength check, freeing itself or another creature within its reach on a success. The net has AC 10 and 20 hit points. Dealing 5 slashing damage to the net (AC 10) destroys a 5-foot-square section of it, freeing any creature trapped in that section.

Nuisance Trap (Levels 1–4)

Trigger: A creature crosses a trip wire Duration: Instantaneous A falling net trap uses a trip wire to release a weighted, 10-foot-square Net suspended from the ceiling. The trip wire is 3 inches off the ground and stretches between two columns or trees. The first creature that crosses the trip wire causes the Net to fall on it. The target must succeed on a DC 10 Dexterity saving throw or have the Restrained condition until it escapes. The target succeeds automatically if it’s Huge or larger. A creature can take an action to make a DC 10 Strength (Athletics) check, freeing itself or another creature within its reach from the Net on a successful check. Detect and Disarm. As a Search action, a creature can examine the trapped area and make a DC 11 Wisdom (Perception) check, detecting the trip wire and the suspended Net on a successful check. Once detected, the trip wire can be easily cut or avoided (no ability check required). Destroy the Net. Reducing the Net to 0 Hit Points frees any creature trapped in it (see “Adventuring Gear” for the Net’s statistics). Set the Trap. A creature that has Thieves’ Tools and all the trap’s components (including a Net) can try to set a falling net trap, doing so with a successful DC 13 Dexterity (Sleight of Hand) check. Each attempt to set this trap takes 10 minutes. At Higher Levels. You can scale the trap for higher levels by increasing the weight of the Net, which increases the save DC and the DC of the Strength (Athletics) check as follows: DC 12 at levels 5–10, DC 14 at levels 11–16, or DC 16 at levels 17–20.
