Trapsmith: Get Gavin (Part 2)

Study for the dead alchemist -- Elihu Vedder

10. Bedroom

Two strong wooden doors lead to the terrace. The bedroom is very spacious. Luxurious linens cover the bed. If taken, they could fetch 75 gp.

The doors are currently locked, and  it requires a DC 35 Disable Device check to open them. The doors are of strong quality and have hardness 5 and 20 hp each; their break DC is 25.

11. Terrace

The terrace is where Gavin entertains guests, and he does some of his best work designing traps there. Carefully maintained plants and flowers line the railing. Because the terrace is vulnerable, Gavin has protected it with one of his better traps.

The enervating net trap involves a trapdoor located in front of the terrace doors. Setting off the trap means that the targets fall down. They are caught by a steel net that drains their vitality. Succeeding on a DC 30 Perception check reveals the bypass switch.

Enervating Net Trap    CR 8
Type mechanical and magical; Perception DC 32; Disable Device DC 25
Trigger proximity; Reset automatic; Bypass switch
Effect trapdoor (succeed on a DC 25 Reflex save or fall upon the enervating net) multiple targets (all targets in a 10-ft. square)
Effect entangled (all targets falling upon the net are automatically entangled)
Effect enervating net (1d4 temporary negative levels each round, treat as the enervation spell); multiple targets (all targets caught in the net)
Effect fall (escaping the net results in a 20-ft. fall, dealing 2d6 damage)

An entangled creature can escape with a DC 20 Escape Artist check (a full-round action). The steel net has hardness 10 and 10 hp. It can be burst with a DC 30 Strength check (also a full-round action). The trapdoor is of strong quality and has hardness 5 and 20 hp; its break DC is 25.

1 thought on “Trapsmith: Get Gavin (Part 2)”

  1. This was pretty epic Darkjoy. I’ve been following your series for awhile and this was a nice change of pace (though a return to form next week is welcome.) Just in case you’re running out of materials lets see what you can do with: An accordion, A dart board (complete with darts), empty bottle and broken bar stools (no booze its a bar that has seen a brawl.) Go nuts :)

    I’d also love insight into how you arrive at the DCs and bonuses to hit with your traps (trapsmithing while entertaining isn’t my bag.)
