Fiddling with Traps

When Castille finds the tripwire he stops dead in his tracks. As the water churns below, he has become increasing anxious. The thought of taking a dive has only brought back bad memories of his experiences attempting to stay afloat in the lake near his childhood home. Aware of the consequences of falling in, Castille, motions for Kaspar to take a look at the wire.

Kaspar moves ahead of Castille and crouches down with his tools in hand.

While Kaspar doesn't have any relevant craft skills, he does have quite a knack for disabling devices. Taking a look in the Player's Handbook, this seems to be the applicable skill for disabling traps, no?

With a pair of wire clippers, Kaspar sets to taking out the tripwire. No need to hurry here.

If he manages to avoid calamity, the half-orc will also look about for some way to mark the weakened section of catwalk. If the walls are willing, he'll scrape some of the clay away. Crushing the scrapings into a powder, he'll attempt to sprinkle some along the walkway.

I'm hoping the pipe is colored differently than the catwalk grate here. If not, then obviously this is a pointless exercise.

"I don't know if we'll be able to see this on the way out," Kaspar explains, "but if we're running full speed from some sewer-demon I sure'd like to know where to leap. And I bet you don't want to fall though neither."

Now with Kaspar leading the way, the team proceeds onward to explore the obscured feeder pipe.
